Problem with the Pandaria Login

Soo this is what happened. Yesterday I played with no problem, and this morning when I tried to log in, it got stuck on Connecting. I went through some guides here on the forum but nothing helped. Then from a thread I downloaded your old game with the molten realmlist and connected with no problem. I deleted that and downloaded again the official game from your download section (after I deleted everything).

Again, stuck at connected. What could be the problem? If I go back to the molten-wow game it will spam my chat that I'm using an old version. But the new version doesn't work for me.... or it worked, until now. I have no idea what happened. Any help please?
