Wyred 4 Sound Driver Issue

I installed the driver on my Windows 10 machine and used my W4S uDAC-HD for a few months. It sat inactive for another few months, and when I plugged it back in, the unit was not functional.

I went to the device manager and the drivers were correctly installed in both "Audio Inputs and Outputs" as well as "Sound, Video and Game Controllers". What was new was under "Other Devices" was Wyred 4 Sound DFU, which said the driver was not found (there is no driver).

Windows Troubleshooting can't help, and W4S has no clue what DFU is either. Searching DFU on any search engines gets you information about an iPhone mode.

Thanks for any help.
