I recently started playing on Stratholme before it shut down and now I'm having issues restoring my characters from that server onto the new Nighthaven. Is it possible to do so, or do I have to start from scratch? I've tried doing the restore characters link but unfortunately it says authentication failed or password is wrong even though it is not. (I've tried many times). My character are over level 10 and I don't know how else to get to my old characters.
