Account is flagged?

I posted earlier about some issues we were having connecting with multiple computers / accounts on the same network. We have found a way around it, mostly, but have discovered a new issue.
My account, Faethia, appears to be flagged for some reason. No matter which password I try , the new one I changed it to or the old one that was working before, I get a "unable to connect" message. When I try again I get the "account has been closed" message. When this happens everyone else on our network cannot connect, even if they try with a brand new account. So it seems that no matter what password I use it doesn't let me connect and then flags our network IP and keeps everyone from logging in.
Any help would be appreciated.
