Ok im running vista and i had SEVERAL problems getting certain patches to work. have any of you not been able to get a patch to work and theres already a default prgram to run it u dont want? well i spent quite some time since im prtially new to vista figuring out y my patches werent working. well i came to the conlusion that they werent working since the ".mpq" after them were not capitalized (.MPQ) i had NO iea how to rename them since after having it open with a default program the ".mpq" was no longer after the patch name. well it is very simple to change this and many of u might kno this but if your like me and had trouble this shows u how to make these patches to work. all u do is once your in WoW's data folder containing the patches go to Tools at the top, folder options, view, and uncheck "hide extensions for known file types" this now makes the ".mpq" show up and u can easily rename the file and change them to capitol ".MPQ" plz dont flame this is just for the people who are having trouble and cant get answers!
