During the firmware update phase of the DCM 126.96.36.199944 I hear several system chimes as the devices come and go but ultimately the upgrade fails with "the camera firmware may be corrupted" "error code: -4". I'm running fully updated Windows 10 pro on a Core i5-6500. I have an F200 camera which worked fine a year or so ago in a different computer (which I no longer have). It's plugged into a blue USB 3.0 connector. There were two log files in my FWUpdateLogDir which I've attached. Thanks for any suggestions.
