Error Code:BLZBNTAGT00000AF0

[Kozzae-4668 (Kozzae)]

The error fortunately does not prevent the game from running, if you are using the world of warcraft shortcut to start the game, change to the battlenet launcher.

Folder does not contain the correct version

Verified I received the error running the wow short-cut from the start menu, but not when hitting the play button on the launcher app, so the work around is the start the game from the battle.net app launcher.
