My problem is that I have halo 2 for windows vista and when I put it in the
DVD drive it doesn't start. I have no idea what the problem is, and I was
wondering if someone on this forum would know.


I'm running Windows Vista Ultimate

my computer specs are

Intel Bad Axe 2 motherboard
Intel Q6600
4GB Gskill memory
Radeon HD 2900XT
