halo trainer

i downloaded a halo trainer and i try to run the trainer (game is in cd drive) but then it says cannot find main program.exe

does anyone know how to fix it or what to do theres no read me or anything

make sure to extract the trainer into the game directory. i got that far, started the trainer, started the game, and as soon as i used one of the keys to activate say, infinite ammo, it closed the game and gave me an error message. sry, that doesnt help at all, does it? oh, i have a Wii, do u want me to add u to my adress book?
