My rating for the product and support is Excellent!
I remember the issue - the 'JModel' class was not being loaded properly for a drop-down menu module that was installed. After a small bit of code was inserted into that 3rd party module and it's all good now :)
Just for your information, I will be releasing a brand new version of this component for Joomla! 3.x within the next few weeks - and it WILL have database logging capabilities for the recommend emails sent!!!
Thanks again MojMaestro!
