How to enable "Visitor Has Role" option in Popup Pro?

I've installed Popup Pro, and am looking for the feature "Visitor Has Role" option so I can display specific Popups per role.

Before I purchased, I was sent a screenshot by a support person that showed this option, however now that I've installed, it doesn't seem to be listed in my list.

Is there something I need to set first?

Thanks for your time,
