Trainer seems to note a different patch than is what is in the game, so i'm not sure if the trainer is wrong, or just the date. screenshot attached. Since the game and trainer work fine together, just gonna assume a typo.
Yes I am experiencing the same issue. The latest trainer says Build June 5 2020 but the latest game version is Build November 27 2020 but the trainer works fine. Enclosing a screenshot..
I played the GOG version yesterday on Windows 10 and all the options I used (NP1, NP2, NP3, and F4)worked flawlessly. Last night I pulled the trigger and upgraded to Windows 11 and now when I press F4 the game crashes. Can you test it to see if it can be replicated on other Windows 11 PC's? The trainer maker can send me a PM and I can send a Pastebin link with all my DXDiag info. I don't think it's allowed to post links here.
... the GoG version isn't supported
