I usually seek to avoid commercial extensions because Joomla is an open source system and I don't mind having to take the time to figure things out on my own. I don't mind paying for an extension if it's good and the developer is willing to support it. In this case, the developer does not seem to be willing to support it whatsoever. I've setup this extension fine, but it does not integrate smoothly with Community Builder so I submitted a ticket for support. I didn't receive my first reply for a week. Suddenly, the ticket was closed and ignored. I submitted a second ticket. Checked it a couple days later. Closed and ignored. I submitted a third ticket... closed and ignored. My recommendation, do not buy any extensions from this developer!
I checked up your tickets. I see there was some issue.. But all your tickets seem to be holding on "Requires Feedback" . So some input from you in needed on them. There was some issue in the ticket system after we upgraded it due to which a ticket was closed. But none of the other tickets were closed they were replied to changing their status to "Requires Feedback". If you login & see you should see them.
