I have the german cut version and no one of the trainers worked to yet for me, germany sucks really. I´m 31 years old and still can´t play games i wish or cut like hell.
If i start the trainer the game freeze
The trainers are made using the American version of the game. German versions are notorious for being unique in toning down the violence due to the strict content guidelines that Germany enforces on video game content. Because of these differences, the resulting end product differs in execution than CHU's versions.
Because of that, compatibility suffers quite a bit. You can try a No-CD fix however it cannot be guaranteed this will resolve the problem.
