thanks all--I did send Accuquilt a help email message and they responded with the directions to do a "hard reset" that were more complete than what I found on the Accuquilt FB page. Will try that tomorrow morning and if it doesn't work they also informed me how to test the power cord and then if those are not the problem, how to return it to them for repair (although several people on the FB page said they basically replaced theirs). I love this die cutter--so accurate, so fast, and sure saves my Carpel tunnel and bad shoulder.
