Been ages since I've run launcher, thanks to the stupid anti virus crap it was causing, so I'm not surprised it didn't do anything when I fanally found it. WoW.exe only seems to download things when the patch goes live (and thanks to my ISP throttling torrents, it takes forever to get patches), so thanks for the heads up.

Just started up BackgroundDownloader.exe, and it's downloading WoW-3.0.9.9551-to-3.1.0-enGB-patch. It's pretty big at 594 MB.
