Hello,
I purchased this plugin today. I am having some difficulty getting this installed onto my site.
First attempt, I uploaded 'out of the box' and received this error message:
Error! Could not find a Joomla! XML setup file in the package.
I then noticed it had to be unzipped first - just to find an additional zip file inside.
Unzipped that one again... just to make sure the proper files were in the second zip... they were. It also included the an XML file.
So when uploading/installing the proper zip file, I received the same error.
Error! Could not find a Joomla! XML setup file in the package.
Help me Obi-wan Kanobi, you are our only hope.

I'm in the same boat as you Same error too, can't figure it out, hopefully someone answers soon!

Nevermind, i had a moron moment, forgot I ahd to use the community builder plugin installation routine. For the other gentleman so affected, that will work

Sorry, I keep having issues with my forums. I'm not getting notified of new posts. I've been a little busy to check, but glad to hear that you found the right solution!
