I have bought Call of Duty for $50 beat SP then moved to MP. I downloaded Heat of Battle Version 3 and i put in my CD key then joined a server. Before the map started loading it would always say " CD key is invalid Please Go to Multiplayer Options and Enter valid CD key" :mad: Has anyone experienced this problem? any suggestions would be helpful. Thanks in advance:uhoh:
You shouldnt have to re-enter your cd key for heat of battle. Go to this website and post your problem they will get you in game in no time.http://hob.mikesmarauders.com/?DorseyInc.com
