Game Apps not working with iOS10

Since the update, I have been unable to play Snoopy Street Fair. I have been playing the game since I got my first ipad. When the game loads up, it comes up with a black screen that says my game is corrupt and I need to choose a backup to restore the game. The back up dates that are offered are from 2014....which would make me loose all of my progress and purchases since then. I play that game every day. NOT happy about what is going on.
