I have the steam version of MP3 and after pressing F1 the game crashes .I live in Shanghai and since the game is not available in the chinese version of steam I had to connect to a german server to buy and download it. Maybe I have the german version of the game and for this reason the trainer doesn't work...I don't know
I can not confirm, but While "No Damage" was active it did seem the the "Strong" enemies did indeed take more damage than i remembered, them taking playing the game without the trainer.
Head-shots are not the only way, but a considerable amount of ammo was required to kill them.
Since I have the Retail version of the game and don't really feel like running the risk of being banned by R*, is there any chance of a trainer being made for the legitimate Retail version of the game? Right after this post I'm going to submit my version of the .exe file (through the Submit Cheats button), if that helps.
EDIT: It doesn't seem to want to let me submit it, as each of the three (3) times I've tried, I've gotten a 404 error...
We don't plan on making any additional versions of the trainer. There are at least 20 different exe's for this game, one for about every different country you can think of. It will become too much of a headache when the game patches. Either buy it on Steam or use the no-cd fix with the retail trainer.
