  • Account Issues

  • I purchased without making an account and I can’t login to KSP Store.

    After you checkout from KSP Store, the system will automatically create a KSP Store Account with the email address and password you type in the Checkout Form. You should be able to log in using those details and the instructions here. If you do not receive a confirmation email, due to your email provider blocking it, don’t worry, you can still log in and download the game.

  • When I try to login, it says “There is no account associated with this e-mail address”.

    Maybe you mistyped your email address when you create your account or filled out the Checkout Form of KSP Store. Send an email to KSP Support explaining your problem, your KSP Store Account email address and your Invoice ID. Note that the Invoice ID is NOT the Transaction ID and NOT the Receipt ID.

  • I’ve used the password recovery feature to reset my password, but I didn’t get any recovery email.

    Well, first of all be sure to check your spam folder. We also have realized that some email providers (Verizon,,, Comcast, etc.) have blocked our domain ( and IP Address due to their strict incoming email rules. They added us to their spam lists, so you won’t receive any email from us. Send an email to KSP Support explaining your problem. They will reset manually your password and ask you to change your KSP Store Account email address. If you are using an account from Gmail, Hotmail, Yahoo, or something similar, you might want to check your spam folder before asking for help, password-recovery emails usually end up in the spam folder.

  • I currently have a weird auto-generated password, but my own. How do I change it?

    Log in with your current password and click the My Account button, go to the bottom of your profile and click the Edit Profile button. There you can edit most of your account information, including the password.

  • I used the password reset, but the password you sent me doesn’t work. What’s the problem?

    90% of the times, this is because when you copy-paste the password off the email message you copy blank spaces too, the log in system evaluates the full string, including blank spaces, so if there are blank spaces, the password you used is different to the one in the database, and thus fails to log you in. Make sure you don’t get blank spaces.

  • I bought the game on the KSP Store, but I want it on Steam. Will you give me a Steam Key?

    In general no. The option to transfer KSP Store licenses to Steam is only available for those who bought KSP before it originally came out on Steam, March 20th 2013. Note that if you do qualify for a transfer and choose to do it, the process is OPTIONAL and IRREVERSIBLE. If you transfer your purchase to Steam, you will no longer be able to download or update the game from the KSP Store. To move to Steam, log in to your KSP Store profile and you will find the button to start the process next to your download link. If you can’t see the button in your profile it means you purchased the game after it was on Steam and you are not eligible, no exceptions, please don’t insist.

  • I bought the game on Steam, but I want it on the KSP Store/GOG as well. Would you activate my account for download?

    No, sorry, the migration will not work that way. If you bought the game on Steam, you will only have it on Steam. To get it in the KSP Store too, you will have to purchase it here. Do keep in mind that the Steam version is DRM free, so it can be played offline as well, so you’re really not missing out on anything with the Steam version instead of the KSP Store one.

  • How can I receive support in a language different to English?

    You can just write an email to in the language that you feel most comfortable, this does not guarantees that you will receive an answer by a native speaker of said language. This FAQ is also translated to Spanish, Russian, Chinese and Japanese.

  • Gameplay Issues

  • The game gets to a screen with a slideshow, a loading bar and some clever game tips, but it’s stuck there, the loading bar doesn’t move. What can I do?

    This most likely due to you having moved the KSP executable, ( for mac or KSP.exe for windows). You are not supposed to move anything out of the KSP root folder (KSP_win or KSP_osx folder). If you did move it, please try putting it back, then everything should work. Also keep in mind that sometimes mods break the game causing it to fail to load, if this started happening after you installed mods to your game you may want to remove them. If none of the above is the problem contact us to get another solution.

  • I installed mods on a previous version and upon update the game is acting weird or flat out crashing. Why is this?

    Mods are very likely to break from one update to another, we suggest you delete your mods and wait for the mod maker to officially state that they work with the newer version before downloading and installing them again. Or roll-back the update to the previous version where you know mods work fine. Instructions to do that on Steam can be found here. For the KSP Store, since updating is on-demand, if using mods it’s recommended to hold from updating to a new major version until you know all the mods have been updated. If you already updated and want to roll back, downloading the previous version installer and using it over the same folder should do the trick.

  • When I start the game, I get a strange error that says “GetThreadContext Failed” and the game crashes.

    This is most likely about a background program interfering with the execution, the prime suspect is an Antivirus, but it may be something else. Try turning the Antivirus off and see if the game starts okay. It should also help to update your graphics drivers and/or Video BIOS.

  • Will Kerbal Space Program be released in other languages?

    Yes! On PC, KSP is already available on Spanish, Russian, Simplified Chinese, Japanese, German, French, Portuguese and Italian.
    On consoles, we’re continually exploring the possibility of further language updates to Kerbal Space Program Enhanced Edition, and will update the community with any news.

  • Miscellaneous

  • I uploaded a gameplay video to Youtube. Is it okay for me to monetize it?

    Yes, by all means. If you are having many views and want to seize the opportunity, go ahead. We just ask to be given credit, a mention and a link to our website is enough. You must also make it perfectly clear that we are the copyright holders of KSP.

  • I want to use KSP for a school, museum or another educational related project. May I?

    Yes, Kerbal Space Program encourages ‘Space Education’. We partnered with TeacherGaming and created ‘KerbaEdu’ for schools, so you can visit their website to contact them and know more about this.

  • I cannot access the Forums/Spaceport or the KSP website. What should I do?

    Send an email to KSP Support explaining the situation and don’t forget to tell them your IP address, if you don’t know it you can get it from here.

  • When is the next release coming?

    Short answer: When it’s ready. This also applies to the console releases. Long answer: It is very hard to estimate a release date for any software product because unexpected things happen all the time, that’s why we don’t give release dates, not even estimates. We used to do it before but we could hardly ever release on the promised date, which caused people to get upset, and since we don’t want to disappoint you, but above all we don’t want to rush a release of a potentially buggy and untested product, we’ll keep the timeline to ourselves and release the game updates when we feel they are presentable to public.
