Thank you in advance,
Well, it has to be something different on your side as the trainer is like 4-5 years old and there's been no game update in quite awhile.
The most common problems. Did you right-click and run trainer As Admin? Did you either add it to your Exclusion list or disable your AV and firewall? You don't have more than one version of the trainer in the game folder? Try moving the trainer to the folder with the game's exe file.
Other than that...
