I bought new dance mats for DDR about 2 months ago. Yesterday they were working fine in the morning, then when I tried again in the afternoon, neither one would respond at all. I tried using only one mat, switching the mats around, unzipping the mat to make sure everything seems to be connected, restarting the ps2 system and nothing works. I plugged in the old mat which is torn and that one would work. But with these newer mats I can't even get the game started. They worked perfect for the last 2 months and do not seem to be worn out, it's as if there is no power to them at all.
