Can't load into the game.

For some reason, I can't load any character I have into the game. An hour ago I disconnected from the game while doing an rdf in Deathwing server and I cant get back into the game. I can get up to the character select screen and choose a character but the loading screen that comes after stops after reaching 100% and stays there. It does not load me into the game and the I get stuck at the loading screen.

I have also tried loading other character on the server and also on the Lordaeron server, same problem with loading screen getting stuck at 100%. Haven't been able to play for an hour now. Please help.

Edit 1: I get disconnected from server after the loading screen stays at 100% for five minutes. Deleting cache did nothing. Restarting internet connection did nothing.

Edit 2: Started working again three hours after problem started. Still not sure what happened. Any suggestions?
