Game incompatible because of Bnet update

[BaGua-1534]

Last night Bnet updated my game from 10.2.7 to 11.0.0.55566. 11 isn’t even out yet so my version isn’t compatible with the game anymore and I can’t log into any Realms. There is no roll back. Updated just tells me I am up to date. And scan and repair finds no issues. I have the new loadin screen also.

Per Demoxinigosa over on the tech support forums:

So, the solution to this is apparently COMPLETELY remove Battle.net (including the Battle.net Client itself), THEN reinstall. You should make sure to back up your WTF folder as well because apparently uninstalling WoW decides to remove all of your settings with it.

I tried it and it worked for me also.
