a few hours have already passed since this happened, but..

we had won EoTS and i noticed that i couldn't leave the bg.. i even tried to shift+spacebar and press leave bg again. nothing!
my only option at the time was to just close wow and try to reopen it (that usually works the problem out), but not this time..? i can log in to all my other character except this one, it says "no instances servers are up" or something of the sort.. what are my options? all intellectual help is appreciated. ;]
