Well... I finished the game yesterday. It took a while to understand the way to win the chopper sequence. Heck it took a while for me to get the elevator acid bug shootout... Now I'm shelving this game.
Ok, first thank you for the trainer. Now on to my issue. The trainer will not recognize the game. I turned off antivirus, ran as admin, put it in the game directory and matched up the version. both trainers here and the ones over at cheatscapes won't work. It is a retail version of the game.
It's the Limited Edition with extra content for multiplayer. But since I do not play multiplayer I did not activate that so it is just a basic retail game which I have updated. The latest trainer should work for it.
