CVar accounttype

Switching this CVar from any setting to "CT" can resolve issues with loading into the game due to missing files - the Launcher will stream any missing files in as necessary. Usually, this tends to happen with users on Classic accounts unable to log into large cities.

This cvar saves the account level that was last logged into the game.

Default Setting

 * ? :Depends on the used expansion level

Possible Settings

 * CL :Classic WoW
 * BC :The Burning Crusade
 * LK :Wrath of the Lich King
 * CT :Cataclysm

Changing this setting
In-game, type the following /console accounttype setting
