Error connecting to servers after changing Profile name

[gsand]

Hi Folks, I've just downloaded and purchased the game, It seems great fun, but having some problems with online play.

First time I played in multiplayer, I didnt set a profile name (I am registered) and entered the server as "unnamedProfile". After leaving the server to go and change my profile name (Not create a new profile, just rename), I cannot get back into the server I was playing on. As soon as I go to join an ingame messagebox just saying "error" appears.

Has anybody else experienced anything similar?
