Thanks Golfdriver97 for the welcome message. I find this forum very helpful, and everyone is so willing to assist - this was my first question and I am overwhelmed about the response.
@Leenakt, I would love to contact Google, I will contact them through
https://support.google.com/googleplay/answer/3107761
I suspect Google Play might have removed this app from their store, but surely I should then be able to get the backup app/link from their servers, surely they would not remove all traces especially if it is a purchased app?!
I will keep y'all posted.
PS: I found the email in my archives to comfirm purchase. I will also contact the third party vendor: Golden Spiral Software, LLC
