[Kerbal Space Program] I can no longer access my KSP game downloads from my Kerbal Account

As of August 31, 2021, your KSP game downloads are now available from within the Private Division Account portal. Your KSP Account used to access the game downloads has automatically been migrated to the new account system.  

Visit the Private Division Account portal, enter the email address you used to purchase KSP or create a KSP account with, and follow the upgrade instructions within. Once you have completed the upgrade of your account, you can access your previous purchases from within the “Game Download” section of your profile.
