It's disappointing when this happens, but thankfully, I've noticed on my iPad that the crash recovery is pretty helpful... make sure that Rush is completely closed, then open it again, and WAIT FOR THE PROJECT TO FULLY SYNC. Sometimes, even with great bandwidth, it needs time to make sure all the assets (especially long video clips) have been properly synced to the project (and any other devices you might have Rush running on as well).
Let us know if you were able to recover it! Hope this helps...
