Crashes

using minivan now for over a year was a great product and still is. Just one problem is that with our 8gb 2nd generation i-pods running ios 4.2.1 and minivan 5.3 it crashes on all our pods. We have over 30 pods and it happens too often. When you spend over an hour a night trying to unfreeze the pod no canvassing is getting done. Help
