What is this 15 day trial?

Purchased Yummysoup on Feb. 07 2012. Found that the importing feature worked well and I had lots of fun importing and organizing hundreds of recipes. Out of the blue after using it for about a year I received a little window telling me that my 15 day trial period was over and I must go to the App store and submit 14.99 for a working copy or enter the code to get my program going. Mr Hubbard tells me that there is no such qualifying code and he has been trying to identify my purchase. After some time there are no results from him, so I feel that he feels I am some scam artist trying for a free copy. When I click on my YummySoup icon I get the screen which describes the program and it says the program IS installed, but I cant run it. I wonder if I send pictures by email of what I am seeing if that would help. A potentially excellent programme, works for me! Now I wish I could recover all those recipes. I wont be buying more applications from the App Store until I get this straightened out
