I didn't play since a few day and when I tried to connect I had the old WoW Ban message : ""This World of Warcraft account has been closed and is no longer available for use. Please go to http://www.wow-europe.com/en/misc/banned.html for futher information".
I tried to change my password, but same result.
Don't know if I had been hacked, but what a pity when you are a casual gamer, not a cheater and you are treat like you where one :'(
