I am still getting the error after reinstalling and using a new key.

Also There is a issue when letting guests see the chat, it's quite important that guests see my chat but when they speak and one breaks the rules it's impossible to tell what guest it was, if the gusts were numbered it would easily solve that.

I would recommend submitting a ticket.

OK, what about the guests thing ? I can have 2-10 guests in chat sometimes and quite a few of them join up to the site.

I started trying to add guest support quickly today, and found out it's not going to be so quick. A lot of changes need to be made to support guests 100%.

That's going to be coming in a future version, probably 1.1.
