Joomla Free extensions

I purchased the JO Facebook Group product last week (Order ID. 1424171435 )

In the main everything went well with the purchase, the upload of the extension and the implementation.

However, I have two issues:-

a) Firstly, there is no LIKE image appearing - the like.png file is in the directory and firebug suggests it is there but it is not being displayed for some reason?.

b) Secondly, although the name of the person making a comment is displayed and the image, the corresponding text for the comment is not being displayed.

I have attached screenshots
a) of what my Joom Core Group Page Looks Like and
b) of what my Facebook Group Page looks like
to demonstrate the two missing elements.

Please can you advise how to rectify the above and provide a solution?

Thanks in advance of your prompt attention.
