Every time I launch the game through Frozen Throne.exe and hit battle.net, it goes through a quick patch process, tabs me out and gives me a CD-ROM drive error. I close it, it patches the game, launches and I get into battle.net. It repeats this process every time I do a fresh launch of the game and try to log online.
If I launch the game through Warcraft 3 Launcher.exe instead, it simply gives me the "update successful" window, launches the game proper, and when I log onto battle.net, it doesn't start the patch download and lets me in just fine.
So on one hand it's a problem, but on the other hand it's not a problem. It works, but it obviously doesn't.
Peculiar.
