Popup Not Writing To Database. Unable To Save Popups.

Free version of Popup stopped working on upgrade.

At first it simply wasn't displaying the pop-up.

Plugin does not delete its entries from database. It should. I did so through WPDBSpringClean.

Reinstalled and then it stopped being able to even save popups.

Upgraded to the paid version in hopes that it would start working.

No Go. Please help.
