Everytime I try and click login and select my character, it does nothing and gives the message "disconnected from server"

Anyone know what thats about?

Yeah it is a display for if you can't connect to the server.

Tried clear cache/cookies?

its on a work computer if that helps

have had no problems playing up until now

Probably your IT department fucking with you so you do work

have it worked on your computer at work before?
Maybe they have blocked some ports so you can't play?
That was pretty common before that users on this site tried to play the game on their job before but they weren't allowed to connect to the game. Did get disconnect all the time.
