For about 2 weeks now i've had some problems with getting stuck at my loading screens, it can be when entering a dungeon or switching from normal to HC.
I am also having problems logging in and i get stuck at connected.
After a few tryes i eventually get in but then it sometimes happens that i get the "character not found".
So i ask you now, how do i fix this? Its driving med mad.

PS: I did ask on the wow-eu forums but the answer i got was to launch wow as administrator but that didnt solve my problem.
