Technical Can't connect anymore after first login

[Charrr]

I installed and played wow wotlk for the first time today, but now when i try to log in again i can't connect. It keeps hanging on 'connecting...' and then telling me its unable to do so. Also my video settings reset every time i launch the game now, idk if that's normal.

Restarting my pc fixed the problem :)
