I have a 2nd generation 32g ipod touch. It's running os 3.1.2. I love extreme sledding, but when i get to whistle peak on the lower cirque course, i get to the fourth gate and the app quits. I tried deleting the app and reinstalling it. that didn't work. Please tell me how to fix this. Thanks.

I can reproduce this - and will submit a patch to fix this asap.
