My Sansa Express is dead. I’ve put Sansa into the USB and update window has appeared, so I confirmed it and updating was started, but while device was updating “windows has found new hardware dialog appeared”, I closed it every time but then my updating was stop at 18%, so from there on I cant turn on Sansa, I allready did the hard restart, tryed it on the other pc and so on… if I plug Sansa into computer all I get is "new hardware found! dialog by windws. Device won’t even charge as it used to. Is there anything I can do before I return it to store?
