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.
