I am having the same problem. I am running patch version 1.0.17 with the matching trainer. I am using a cd to play the game, so I don't need a no cd key version. My antivirus is turned off and so is the game's punkbuster service. I am running 32 bit Vista. I start the trainer, then the game get to the enter screen and hit F1, hear the confirmation and get to the loading screan at which point the game crashes anyone working on a fix for this? It's very frustrating, and this is happening with all trainers for this game.
Update: I recently updated my game to version 1.0.18. I bought the trainer for this version and now when I try to use it the game freezes and whenever I hit a control nothing happens, it's not the controller I'm using because the keyboard doesn't accomplish anything either. If we're paying for this why can't you make sure these things work? I hate to sound rude but it's been days and we all seem to have the same problem and no one has done anything to fix it or even let us know what's wrong. I can assure you that in my case, everythingin the troublshooting guide was covered and everything matches.
