How to make trainer work
 

I just downloaded the trainer for Fable ii. I disabled my norton protection because it thinks there is a virus. I start the trainer and then start the game. I activate the trainer in the game and then hit a key , say numpad 3, and I hear that the function is enabled but now I don't know to actually do something. Numpad 3 is supposed to add 25 things but nothing appears to happen. I really feel stupid but how do I make this cheat work???

Are you sure the trainer is for the same game version, language, distribution media, whatever that you have? (No idea, just a general question.)
