i bought Batman: Arkham Asylum for the PC this weekend, but i have the problem that before i can play the game, i need to adjust the disk several times before my PC will even read it. once it's accepted, though, it works fine until i reboot my computer. it's only with Arkham Asylum, not with any other disk. fallout 3, for example, just works fine.

does anyone have any idea on how to fix this?
