I basically had to format it and install original firmware.
Go to http://voxrightnow.custhelp.com
search "updates and firmware upgrades"
Topic is "How do I update the firmware on my TH1602 mp3 player?"
I downloaded the file and ran it. It will format the player, so store you may want to store the songs somehow.
This went to the 1st version of firmware. After removing it from the computer and reconnecting it, it asked me to upgrade to the latest firmware.
