I ran the halo 2 game disc once made a profile, installed the dlc from a hdd ready download. Original hdd had the dlc already. The installed files match on the 1 TB drive so the install is good. 3 out of ten times when a dlc game is picked in the pregame lobby I get a "Failed to load map" error. Also when I try to join a game that is dlc it occurs as well. When I host a dlc game it works but not every time for the other person I get 1 or more players failed to load map. This occurs with xlink kai as a direct system link connection works every time. Not sure if it is xlink kai computer settings or what?
