What is this suppose to mean... I just bought the MoP patch and a month gametime.

I installed it got the problem ( above )*, uninstalled it and then REinstalled it which took me 3 hours per time. And the result was again ( above )*

My internet has no problems because I can play it on other computers.
I hope there will be a solution for this issue as soon as possible.

PS: I downloaded WoW on new pc
