so i've got the USB 2.0 cradle for my DMS......everything is plugged in properly, power and usb to the computer, but when i plug in my DMS nothing happens, no lights go on, nothing. it was working earlier, but while i was copying music to it, a box popped up that said another application stopped the DMS and it powered off...now it won't go back on...is it dead? can i get another one from somewhere without buying a whole package??
