Good but flawed

The math problems are just what I was looking for. Level appropriate and perfect for repeat practice. ...but when we go to use the coins that my daughter earns nothing happens except the game suddenly turns itself off. So there was no reward??? That is what was motivating her to answer all those math questions, and then nothing. Bummer.
