Another Client has connected?
I’d drop a ticket to support and also change your email password if you haven’t already, just to check.
You need to check our account security at this website and make sure an IP address you do not recognize has been authorized (and remove it if it has). Then change the password to something 10 characters or longer.

I was just playing and suddenly I got this error and dc’ed to the character screen. I logged back in with no problems.
I’m a little worried, though I did have connection problems before though I am not sure if its related to that.
Also I checked my email and I have no post of a new IP address.
EDIT: I have changed my password. I feel a little bit safe though not sure.
I think you are wise to change the password. Better safe than sorry!
