Hi all, I need some help. I downloaded the demo for WoW (the PPC version as I wasn't offered a UB option). After d/l'ing this 2 GB monster, I double-click the .dmg file and it creates a "drive" on my desktop and opens up the contents in a window. I double-click the file World of Warcraft (OS X).app and it doesn't do anything. I've rebooted and repaired permissions with no luck. Anyone have any ideas?
