Crashes when i try to play Totem or Word birds

This App is gorgeous and well thought out. I couldnt have made a better one myself... EXCEPT FOR THE FACT THAT IT KEEPS CRASHING!!!!! So annoying!! I paid for the german, then the spanish then the SAT, and the Sat keeps crashing! Have I waisted my money on this really? I have given you guys my business, please deliver what I paid for. The spanish has been crashing here and there as well. I hope my German mindsnacks doesnt start crashing on me as well.... smh
