Support or manual?

So does this plugin have any suppport or manual?

I was hapy with poor guy swiss knife but when i purchased rich guy i get no answers back from support or can’t find any manuals from devloper since he said that a function added to the checkout window will work (the same as in demo site).

So far i’m disapointed, and please if someon has maula or something to help me with this plugin i’ll be more than happy.
