SO im running vista (im starting to see why [peopel hate it) and my buddy gave me the downlaoded doom folder he got on a mem stick (everythign works for him), but when i send it to my desktop and try to extract it it says permision is not allowed (im an admin) and sumtiems it says no data (but ti says 1.5 gigs is there) on the mem stick when i try to open it it says please insert the volume disc to continue or something liek that. wtf?
