not able to log on after latest update

was able to log on fine every day until yesterday when zul aman was released. now i cant log in on any character, any account. have tried removing all addons, clearing cache. reinstalled from scratch, and reinstalled by installing wow from my GFs computer(hers works just fine.)

No wow errors or crash messages, i am able to log on the account, see my character list. as soon as i select one and hit play it just closes wow entirely, instantly.

never had this before, would appreciate suggestions since i cant play at all now

thank you!
