have you "Run as administrator"
Yes, I have tried running the trainer as admin and the game as admin, and even both in compatibility mode for XP (I'm on Vista).
That didn't work either
You sure you're using the correct trainer with what patch you have?
Yes. I update the game from the 1.1 patch on strategyinformer, and have the 1.1 trainer from here (since 1.2 and 1.3 are unlimited only, sadly )
Turns out I was using the wrong No-CD Crack for the version of my game. I updated the game, but not the crack. I was still using the one for the unpatched version of the game.
It works fine now! Thanks everyone for your help.
LoL! Good one At least you figured it out. I'm glad it's working for you now.
