I now get an access denied error when I try to join any server. I have checked my login several times and both it and the password are valid. The dialog is as follows:

Access Denied

Please login with administrator privileges and try again

What could be causing this? I was able to access these servers without said privileges prior to tonight (10/3/2015). And if it helps any, I hadn't logged in in at least several weeks, and at most a few months.
