oh, i totally missed that you had given more answers to this.
@night i get the same problem running it on my webserver as localy, an as i said before, its working in Chrome as another user so im guessing its something to do with cookies or something else.
@Glacials yeah i have had that problem as well, and the same solution, just login and then reload the chat. but its not working anymore. and i got both of the error messages in question, at different times thought. And im using the latest Chrome.
I have it running fine as another user in chrome right now, but its annoying when you click a link and it opens on the right monitor in the wrong browser making me unable to see the chat and stuff if im in a game or something else in fullscreen mode.
