Have you fully rebooted, i.e. held the power button > 5 seconds until the powers down by itself, without pressing the power off touch button?
Boy, the NC has so many power down, power up, reset, factory reset, etc. modes, and they share about 2 or 3 different names. Somehow we need a real set of different names for them.
I don't have a 'power down' button, just the button on the bottom of my computer to start it and 'force quit' if necessary.
update-spent 5+ hrs yeaterday and got nowhere. too 'nooked out' to persue it today. Maybe now.
The Nook still doesn't appear on the ADE anywhere!!
