Dan - that sounds goofy to me, to say the least.
The other night I hit pause an extra time and only noticed with less than a song left in the performance (a 20 minute opener)... I was ratehr bummed that I ran on pause.
So, when you checked the deck, it was off and nothing on the screen?
When you looked at the card in the PC, it showed no files at all?
Even the file restore showed nothing to restore?
