Account Needs to be Redirected to Battle.net?

ElvUI freaked out on me and screwed up all my actions bars to the point nothing could be done about it.

generally when UI **** goes terribly wrong, ive always deleted the Cache, Interface, and WTF folders.

started up the game, closed, unchecked "read only" on wtf folder.

now when i log in it says i need to register my account with Battle.net?

i cant find any work around other than to deleted then entire WoW folder and use the back up i made

Probably a stupid question, but you're logging in with your user name and not your email right?

I am sure he is, as am I, but get the same problem
