Was a great game until...

I got through all the medium levels and I loaded the game up to find myself back on the very first level. I went to exit out but the game timer is at zero, the crossbones wont work and no cavemen drop out. I have tried resetting the game through the phone "home" button and have turned the phone off and on and still it takes me back to the same broken first level. Please fix this so I can continue playing. Thanks
