there is a trainer for gamepass and one for steam, which did you download and use?
also, it may be that the trainer only works on steam for 32 bit version of game, (not sure) but make sure you run the 32 bit version if so. Take care to read the instructions and also which platform (gamepass or steam) you are running and that you are using the right trainer.
best,
Cal
I was just about to edit my post when you replied, now the trainer works, I don't know what I really did. I kept trying something, it suddenly gave me "Activated"
Seems like I put the fear in him 😅. Sorry for wasting your time and thank you for re-activating the title notwithstanding it was once retired.
I'm on x64, steam version, didn't test all the options, but most of them work.
If I was to guess, this happened to me a few years ago, the F1 and Numpad keys didn't respond when I was inside the "Instructions" window in the trainer, I needed to switch to "Hotkeys".
