One my World of Warcraft account, I cannot play as one of my characters. I have four different players on the "Ghostlands" server, and they all work perfectly besides one. He is my main character. When I click the Enter World button, it loads fine until the end where it automatically disconnects me from the server. I don't have any time to move or perform an actions for that matter. The problem has persisted for about 5 days. I have great internet connection and a very fast computer. I have been in this area before and have had no problems. Can anyone tell me how to fix this problem? My character, by the way, is a level 52 Undead Warlock. He is in the Desolace. I'm not sure if those facts matter, but I'm trying to supply the most information possible. Thank you.
