before the patch i was using the mazzle UI and you change the interface and wtf folder, which caused problems with the in game when i tried to change it back, i am no longer able to look at the 'looking for groups windows' or my quest log. I dont know what else to look at in order to fix i tried re-installing wow... which was a pain in the butt by the way. It worked for for the first time i ran it, then i tried this morning and i had the same problem. Any idea on how to fix it?
