Great game but...

I downloaded this free game and played it which it was fun until I was replaying the levels for a seventh time and occasionally it would crash if I worked it too hard. I have a 4th gen IPod as well so it runs decently well, i can run that 3d disassembly game without it crashing. so then I bought the full game. When I bought it, it froze a second after then crashed so I opened it again and its crashed every time since I bought the full game. Like as soon as the menu appears Crash. I dont have any other things running and it crashes, I reset it, Ive done just about as much as the iPod will let me and crashes every time. I want the full game.
