Update Problem

Tried to login this morning and received this error message:

An updated version of World of Warcraft is available. Please launch the Battle.net app to download the update.

  1. Tried to launch the game. Didn’t launch.
  2. #1 didn’t work so I closed and relaunched the Battle.Net app and then launched the game. Received same error message and the game didn’t launch.
  3. Repeated #2 many times. No joy.

What Gives?
