"C:\Program Files (x86)\World of Warcraft\Wow.exe" -noupdate
I closed out to do something and noticed this. I tried something I hadn't tried before. Created a shortcut to Wow.exe, and in the shortcut properties, added a -noupdate to it and it let me in! just FYI
Code:"C:\Program Files (x86)\World of Warcraft\Wow.exe" -noupdate
