I guess i could be a little more clear .. lol I just got a quad core 64 , that had vista on it... Sooooo i put XP Pro 64 on it.. Works fine so far it puts all my 32bit programs in a separate program files.. The trainer comes up fine and even finds the cnc.dat file ,, but no voice or any of the buttons work... This is the only trainer i have that doesnt work.. Even the new trainer for dead space 2 works .... So is there a trick or something to make it work ?? Thank You ..
