PHP Code to integrate Q&A plugin to a custom page?

Greetings..
I bought this script:
http://codecanyon.net/item/5sec-run-php/161343
Because Im trying to integrate Q&A plugin to my current theme.
I already tried adding the plugin php files to my theme, also removing the CSS.
Just need to know if there is a code to call back everything?
Or shall I copy the php files raw code to execute it on any page?
Thanks in advance.
