Game Maker Studio 2 Desktop lost my license

I have in issue. For the one year we worked on the project. An dyesterday suddenly my Game Make 2 IDE began to say me I have only Trial version and can't open any of my projects.
I have tried to recover my License Key via YoYoGames site but don't know where should I enter it.
We can't postpone the development for a long time. So, please, can you help with this issue?


There is no such thing as a license key in GMS 2, the only thing you have is the username/email and password to your YoYo account.

If it logged out, simply go to the File menu and log back in from there. If you forgot your password, go to the forgotten password page.
