Technical Account Connection Problem

[Athena1Arca]

Hi, I was playing normally with Mist of Pandaria on Frostwolf, just come into an instance crashes the game. I try to reopen it, but will not start. Restart the PC and connect, after the game starts, but I have to un-ban all conditions of use, as if for the first opening of the game. This fact, however, I noticed that went even lost the basic settings such as audio adjustments or custom graphics settings. I put everything as my taste and I try to access with my account, but can not connect.
I enter nick and password, or it remains labeled "Connecting ..." and locks (for 20min), or exit an error message that tells me "You need to login with the username and password of a Battle.net account and to do that here. " I have always entered with the same data and it always worked. I tried to control my account and it was active...

My email is [email protected].

My nick is Athena1Arcadica.
Thanks for your help.

remove your email address and account name, it is not safe at all and they are useless for your kind of problem.

Do this, delete your WTF and Interface folder and get new one from the MoP torrent https://www.warmane.com/download
