I have a Mac OSX 10.6, and have successfully downloaded WOW and Burning Crusade. I have bought the Wrath of the Lich King on disk as well, but when I try to install it the following messages appear: Installer quit unexpectedly No installer data could be found. If this problem persists, please contact Blizzard Technical Support. I've tried EVERYTHING, such as deleting all my installed WOW data in all the user/shared areas as was suggested by someone else, but all it did was basically reinstall the game without the new Lich King expansion... Please help, it wasn't cheap!
