HELP! Upgraded to Zooper widgets Pro but still says I'm not! topic

Hello all, I recently purchased the upgrade to the Pro version of Zooper Widgets but when I try to save my widgets it still says that I need to upgrade. I have tried to contact the Dev, but still no response as of two days ago. Can someone please advise me on a solution to my ongoing problem? I have rebooted the phone multiple times and still staying the same, that I need to upgrade! Look forward to hearing from you all to see what you think I should do. Thanks for your time in advance.
