Using Crossover Games 10.2.0 on Ubuntu 10.04 LTS (64-bit).
Installing using the crosstie. Crossover downloads and installs the WoW installer fine. When the installer tries to download the rest of the game, it crashes after downloading a few dozen megabytes (out of 147.1). "Launcher.exe has encountered a serious error..." pops up, and the installer window freezes.
