I HAVE LOADED ON OVERLORD LOADED FINE BUT WHEN I GO TO PLAY IT TELLS PLEASE INSERT THE ORIGINAL OVERLORD, OVERLORD. EXE. CD OR DVD. IT IS THE ORIGINAL CD. DOES ANY ONE NO WHAT TO DO. I HAVE OS VISTA HOME PREM.
I'd check the overlord website for any patches ect. You could also try right-clicking in the overlord icon and hitting properties. Then hit the compatibility tab and run the game as if it were running under XP SP3..
