Greetings. I recently downloaded the wotlk 3.3.5a (wod models) file.

I put it on my Hard disk that is pluged in my computer becouse id like to play it from there. My BC wow folder and vanila wow folder work normaly. As i click on wow icon ( the launcher) it asks me if i want to run this file and i press OK, but than nothing happens. i also clicked on it and went to cook dinner and than client opened after like 20 mins but laged out so basicly computer was frozen. any help?
