http://ubuntuforums.org – hey guys i am switching to ubuntu cause i like it alot better than windows but i am having trouble starting up wow. I copied my game from windows to ubuntu and tried starting it up the launcher with wine but when i do it says updating setup files then like 2 min later it says missing agent try again later blah blah blah. so then i try playing through wow.exe but then i get "wow is updating setup files for core game play blah blah blah" or something like that. anyone know how to fix this.
