Well you're brave taxing your iPad with those resource hungry apps on a live performance. And look at it as you were taking one for the team here - do NOT use igrand and Nave on the same iPad live lol. Nah, I do hope it didn't ruin anything too much.

By the way, importing the bank via iTunes filesharing seems to crash Nave, so there's something weird with Nave and iTunes Filesharing (just delete the file again if you're having crashes, and import it via "open in..." On your iOS device).
