Tracking User Registration with Affiliates Plugin

NB: Affiliate Plugin not listed in the drop down menu, so I had to select another to submit this question.

I need the Affiliate Plugin to track WordPress user registrations (not using any other plugin for users/members). While it tracked the click, it did not track the registration.

I intend to pay a fixed amount when this user/member makes a property listing on the site. I am using StudioPress Genesis with AgentPress theme.

Please guide whether this is possible with the Affiliate plugin. Thanks.
