Cool shows but cant save

I used this app today with k-5th graders. They loved it and did an awesome job but when I try to save the program freezes. Ive tried restarting app and iPad as well as reinstalling. Id love to use this in my first grade classroom but, I need to be able to save. I would give this five stars if it would save and not freeze. Help!
