Need help with - PopunderJS - pop script

I bought this script and I have some difficulties to figure out all the features and configs. The instructions are lacking a bit and the seller is in a completely different timezone than me. So Im hoping some one here has some knowledge to use this script more in depth?

PopunderJS is the name of the script and is basically an advanced popunder/popup/poptab script. The script/site has been around for years.

Anyone that can help? Im willing to pay someone for teaching me.
