[Elecraft] K3 Problem Solved!!!!

[pastormg2 at verizon.net]

Well, it seems that the prolific cables do work with windows 10 and the K3. Evidently you can't connect the cable to the P3 and then to the K3. It must be connected directly to the K3. Once I did that the firmware loaded and everything is back to normal. Hopefully Howard at Elecraft will read this. Thanks to all the people that told me to connect the cable directly to the K3.
