Re-install the CPS to replace those lost files.Prolific chip in the USB cable? Probably a clone. Win 10 always installs the latest drivers. The new Prolific drivers spot the cloned chip and won't recognize it. The fix is to roll back the driver to version 3.2.x. Plenty of previous threads on the problem and how to fix it. Don't include your radio model in the search. The problem has affected most USB Motorola programming cables, especially the inexpensive ones.
All of the tops hits describe the problem and the fix. It has nothing to do with Motorola or your specific radio.
