too frequent request for purchasing the pro-version

I’m quite satisfied with the free version I use- I live in Japan and can still listen to my favorite radio station that I used to listen when I was in the U.S. However, every 10 minutes or so a dialogue appears asking if I want to buy a pro-version. This is quite bothersome when I’m using my computer for something else. Other than that I love this application.
