WAS a great app, something changed. Its BAD!

I was loving this app. Now, something has changed. I tried deleting it. Had to buy it again. I was hoping that would fix it. What a wast of money. It still doesnt work properly. Freezes at the end of a game. Doesnt hold previous games. I dont know what you did to it, except that you ruined it.
