Events + Not Recognizing Paid Ticket Status

Hey Guys,

I've got the Events+ plugin setup, using GravityForms to process the registrations for unregistered users. Once setup as a registered user, people can register and pay for the events but the PAID status is not updating in Events+. In fact, when the user is done paying for the event, they are brought back to the event page where they are shown a message telling them that they have not yet paid for the event.

How to fix?

Pertinent pages:

Registration Link, for Unregistered Users:

If you need access to Admin, please e-mail me with your request. Much appreciated!
