When I join a server on wow, I can play in about 5 seconds until I get disconnected by the server. My friend have tried to play on my account, but he got same problems. (he have tried on his own internet) Atm I have Cataclysm Trial activate, and I have bought cataclysm. I wonder if the trial can interfere the real cataclysm ?

I really need some help from you all.

fast response thanks, I want to play wow !
