Account banned

Hello !
I created my account a few days ago.
As of a few hours ago, I was still able to log-in and play. Now, I am getting "...as been closed and no longer available for use".
Seems like a generic blizzard message. Maybe a bug or some sort ? Also, I have installed today a mod called Questie-3.5r2 that passed Norton and Malware scans. Would it be the mod that causes the problem ?
I greatly enjoy playing on Nostalrius PvE (mainly as klarathemage and stefanhy) and always happy to help others when possibilities arise. I consider myself a good player.
Thank you !
