Wont let me login at all?

[causei]

I was standing in the auction house trying to get gear for a fresh 90 and my game shuts off. I tried to open it back up and when i go to login it makes me try to login to the actual bliz shit. I tried restarting my computer and it does the same thing. So i also tried creating a new folder and putting the launcher in it once more. And again it did not let me. It wanted me to login with bliz. Anyone have any idea's on why it's not working for me? I was on it perfectly fine. Didn't have a single problem until now.. Help :/
