Hi Z8Games People. I have a huge problem with my crossfire, i have loading errors everytime i enter a channel or a room, everytime this happens i have to g to my task manager and close crossfire. SOmetimes i can get in a room and play normaly, if a player join after me in a game i cant see that player name or lag i only see the Revenge Icon on his Rank,always when this happens and the game finish, when the results of the game shows i cant see them because its says *Loading Game Results.Please Wait* and it never loads, then that message box dissapear and i cant see the game results, After this i go to the room as normaly, but i get stuck in there i cant leave the room or join or exit the game or anything, i only can go to my storage,store or blackmarket, once there (on storage,store or blackmarket) i cant do anything even exit or leave the game.
