After install, cd wouldn't spin up, it would just sit there. So i installed updated graphics drivers for my ATI Radeon HD 4550, still no luck. Then closed firewalls..no luck. Then ran as administrator..no luck. Finally I went into compatibility mode and switched to run from XP service pack 3 to XP service pack 2 and now it starts. (i have win 7 64 bit) To change compatiblity mode right click on game desktop icon, choose properties, then compatability.
