Here is the update I did that worked.
Step 1 - Go to: http://patchup.info/downloads
Step 2 - Download the top one (wow-0-14545-Win-final.MPQ - Windows )
Step 3 - Rename wow-0-14545-Win-final.MPQ TO wow-patch.MPQ
Step 4 - Copy wow-patch.MPQ (File we just renamed) to C:\Program Files\World of Warcraft
Step 5 - In the World of Warcraft folder, Run Blizzard Updater and it should update.
Step 6 - Run wow.exe from the World of Warcraft folder (Didn't try it with launcher).
