i have the complete version on steam and can confirm it doesn't work
well i made the trainer, and i also have the game on steam and for the 5th time i have tested the trainer with the game and it works 100%. the version on steam is 2613. if you have some magical way to make steam update the game to 2614 or some other version than i be glad to look at it, otherwise, the trainer is working fine with legit steam 2613.
also, 'doesnt work' means NOTHING and doesn't help at all. i have ZERO information about what version your game is, what version your OS is, where your steam is based out of (US? GERMAN?) and etc.
blame steam in US for having version 2613... not me
best,
Cal
