It's been an annual tradition for me to change the batteries on New Year's Day. This year I was a little late. On Friday I changed them as I always have. Machines on. Sunday I turned them on and lotr said OPEN THE DOOR. Ok, all my scores were gone. Machine reset itself. Dang. My scores weren't that great, but I'll never get my destroy the ring time of 37 seconds again. DESW, same thing, OPEN THE DOOR. Dang dang. What did I do wrong?
