Hey all, I recently got Halo 2 vista and tried running on my brand new HP laptop. I know it can run it. It's a Core 2 Duo, 2gb of ram, and a GeForce Go 7400. When I try to run the game (or even just install it), it acts like it's doing something, and then NOTHING happens. No Halo 2 process, no error, nothing. Any ideas?? Thanks!

P.S.
Speedstep or whatever it's called is disabled (I think).
