Well that scared the hell out of me!. Just updated to the latest version of escribe, the board reconnected and a new firmware showed up. Started to update the firmware and my computer totally lost the plot. Everything locked up and I eventually had to reboot the computer. On restarting, my dna pcb was totally DEAD, the computer recognised a usb being plugged in, but escribe wouldn't recognise it. I was distraught, it took two weeks to get the board to New Zealand and I was thinking, two weeks to get it back, then another two weeks to get another one.. I was not a happy boy when I went to bed! Fortunately while the board was on it's way here, I read nearly every post on this forum.. whew there's lots. Sure enough, I remembered some posts here, went to the tools menu and update firmware manually.. it's alive again! Thank you John and team, I should have known that there is not much that you haven't thought of.
