Pay twice?

I understand that this app has been updated and is now being run by revolution golf. I paid for this app when it was a golf plan instructional program taught by Paul Azinger. I paid for that app at that time. I am now losing that previous app and am now being asked to pay again. I understand the new app, but am disappointed that I lost all of the previous instruction.
