In the "My Subscriptions" area on this site, you can download 3 different files for Joomla 1.6. The first is the main component file, which you look to already have installed. The others are:
1) Social Modules - These are module versions of all of the Facebook social widgets (Like button, fan box, comments, etc). Download this file, unzip it to your local computer and install any of the social modules you may want to use.
2) Profile Plugins - These plugins let you import Facebook profile information into the 3rd party extensions K2, Kunena, Agora, Community Builder, JomSocial, and Virtuemart. If you have any of these systems installed and want to fill out the user's profile automatically, download this zip file, unzip it locally, and install the profile plugins for your system.
Hope that helps, and sorry for the confusion.
Glad you found it, and sorry you missed it before. There should always be the files there, but it's possible they were updating them when you downloaded.
Should you need any other help, just let us know.
