I'm having the same trouble. Trainer for patch #1 worked great...no problems. This new trainer for patch #2 does absolutely nothing. You hear "Trainer Activated" at the main menu when pressing F1, and hear the correct "Activated" and "On" or Off" pressing the numbers from the number pad, but nothing happens...the game actually is now crashing quite regularly.
I have also tried the first 2 trainers...same thing.
Help Please Cheat Happens.
