AlienGPT "Generate" button disabled, just like the mods button

Hello, I just bought the game and can't access to the "Generate" button in Alien GPT with "user not authenticated" message. Also the round mods manager button is not accessable.

Update : when I tried to launch the game under another Windows user in the same desktop it seems work fine. The reason, probably, is in the Windows user name with no latin characters in it. Is it possible to fix this?
