Understanding this plugin

my site is freecoachdirectory.com

I have two issues.

1) Pay with Like isn't showing up on a post or page
2) Members aren't showing.

This new domain is a seperate install from my MU site I'm not drawing from my main database on my MU site I let it set up a new database. If someone wants to sign up here they are creating a new user just for this site.

I can't seem to get the pay with a like plug in to work. Does that have to do with that fact that I'm not pulling from my previous facebook API setting. I thought I read I didn't have to worry about API with this plugin.

All I've done so far is set up my own listing. But it's not pulling anythign to the Members page.
