Freezes up and cannot advance

Yesterday my son asked me to unlock (in app purchase) a new section of the game. Since he is doing so well, I agreed and this became his weekly reward. Unfortunately the new section freezes up and he cannot advance. He is in tears and totally upset. I am extremely upset over the quality of this game! I expect a higher level of debugging before introducing a game program.
