Ok I'm also getting the same errors and issues when it comes to the trainer working with the game. it did work at first but all i get is that error. I have followed the video a few posts ago and also tried different ways and timeings (like while its loading or main menu) and still getting it.
- I have ran trainer as admin
- I have redownloaded trainer a few times and retried.
Not sure how else to figure it out sadly.
By waiting after the game is loaded when you can freely move your character in-game you'll get it to work 🙂
I did change the key F1 to F12 (in the trainer settings), otherwise when visiting the PDA the trainer restart and fail
