yourpagetoday, I finally gave up. As I received absolutely no communication either about the support call or my request for refund, I reported the transaction to PayPal as fraudulent and finally got my money back. I certainly will not be using any plugins from this source again!
I suggest that if others have similar problems use the same method as it would seem to be the only way to get a reply.
Visser, you are the worst Software Developer I have ever had to deal with, providing a total lack of support to your paying clients and plugins that do not work.
Thank goodness I’ve now finished my dealings with you!
