I too wanted to test the light version to see how it worked before purchasing the advanced version but was not able to properly install the code in the one file of Post.template.php manually.   

How do I know I will be able to use your advanced version or that it will even work for me before purchasing it.   I will gladly pay for it if you can show me that it will work with my installation...

I can assist you and even give you a great tool to do it, but I do not give support for lite versions
