In general, make sure you music is backed up else - just in case you ever need to reformat!
If you want to pursue it further, start with a freshly rebooted computer, switch the player to MTP, plug it in, and look for it under Device Manager in the Control Panel. Hopefully(?) it will display with an error & you can update the MTP driver. Good luck!
I only do 7 day check-outs, too, just in case something better comes along. I’m sort of an Overdrive junkie - have to go there everyday just to see if there’s anything new since yesterday!
