Have you tried to verify the integrity of the game cache via the Steam client?
yes didnt help if it helps i didnt start a game yet
is this on a laptop or installed on an external HDD?
External HDD
install it on your main drive this game does not like external HDD's
Your right i just reinstalled it to my main ssd and trainer works. And also doing so fixed my textures and stuttering issues. Thanks 😀
No clue what's going on here, I don't appear to have this problem with other trainers, but... Every time I attempt to launch the 1.07 version of the trainer, my browser is just popping up, saying "The web page at file:///C:/Users/User/Cheathappens/Work/~CheathappensTrainer3729.tmp might be temporarily down or it may have moved permanently to a new web address." I don't know if I've messed up something in the download or what, but the trainer never launches, just shows that.
You messed up, plain and simple 😀
When launching this trainer for the first time, did you get a Windows message and were asked how to open a .tmp file? Very likely you told to open it with your default browser.
Please reset your default apps in Windows, reboot and do what fellow member Weiss suggested: Exclude the trainer exe file and the Work folder located here -> C:\Users\YourWindowsUserName\Cheathappens\
