Sir,

We do need to know a tad bit more information. Than what you have just said.
E.G. What game? Have you ran the game and or download platform including the trainer in Admin mode. Also are you using the correct version to? Also helps to know if you have went through the trouble shooting guide which can be found at the bottom Left of the Web site in the Grey bar!
