This is my error. I've tried the tutorial and that didn't work, I've tried re-installing the game that didn't work. I've tried using the utorrent file and that didn't work. http://sk.hys.cz/items/wow-downloading.png This I don't get, it just says downloading and then it finishes, nothing more downloading. Then I start it and the same message pops up. I've tried un-ticking the file but it still doesn't work.
