Dungeon Queue accepted while on flight path to Oribos

Accepted a dungeon queue while in flight path to Oribos. Transferred to dungeon no problem. Finished dungeon. WoW locks up on loading screen and does not return me to flight path. Restart WoW, now the error message I get says, “A character with that name already exists.” There is no location listed under this character on the login screen. Any ideas on what to do next?

I have had a similar issue in the past and it eventually let me log back in about 30 minutes later. Try logging into a couple of alts and then your locked up toon again.
