I just got the Disqus comments extension and installed it on my joomla 1.7 template with K2 2.5 already installed. Disqus is not coming up in the K2 articles. Is there an upgrade i need to make this work? Please help.

So i found the beta plugin and installed it. Now i get this message on the top of my K2 articles:

Please enter your Disqus subdomain in order to use the Disqus Comment System! If you don't have a Disqus.com account register for one here

I already set-up my Disqus account. Please help.
