Audio Error Message

Enjoyed this game so much the first time, I retrieved it from iCloud to play on my new 6S.
An audio error message came up on a white banner and when I tapped okay the app closed.
I thought Id play it on the bigger screen, but cant until this is fixed.
Neither this version or part two work due to the same error.
