Do you by any chance know what zone it is? If the loading screen looks like this:Then you may want to try downloading a new map for the area, located in this thread.If that doesn't work or if it's another zone, post your character name and a GM will try to move him or her.
So.. did you manage to log in or is this a completely separate issue? I don't want to move you if you're fine and back to RPing.
Done Although my suspicion is that the crash is by the Bronze Doors area... Perhaps give that map a download anyway
