Ice Cream Jump

I open the app after I download it and play a round. I go to the store and see there is a starter pack for only $1.99 that comes with 12,000 Coins. I bought the starter pack, and the app closed down on me. I thought, "Ok no problem Ill just open it back up again." So I did and it closed again. And again. And again. Someone please explain this to me! I have this app on my tablet, and this never happens. Overall, its a great app. But not so great when it closes down on me repeatedly.
