THIS APP DOES NOT WORK :( – ABC Zoo: Writer Review

We just bought this app, & it does NOT WORK :( Nothing happens when we try tracing the number :( We also bought the ABC Writer which DOES WORK when we trace the ABCs like it is supposed to work :) However, we would like to be able to SHUT OFF THE MUSIC FOR BOTH APPS because the music can be very ANNOYING after a while :(
