I posted in another thread where a user reported a similar problem, but it seems like making a separate post is the preferred format.
On my account "Gnullith", I had a disconnect while in IF and immediately after that I was unable to log in. The error message is "This World of Warcraft account has been closed and is no longer available for use. Please go to(...)"
Restarting the computer and trying from a different internet connection does not resolve the issue, and neither has waiting six hours.
I will be very happy to provide more information or help clear any mistakes via PM.
Thanks in advance
EDIT: My guild (and real life) friend just pointed out that it might seem suspicious that I have sent packets of 50 or 60 gold to a couple of guild mates. This was my way (as a player who enjoys trading and tradeskilling more than adventuring) of helping along my guild mates. Again, I am willing to jump through any hoops or clear any questions you might have.
