I switch to another user on the same laptop and succeeded to upload all firmware.
But I did NOT saved the configuration file before doing that.
So far the K3 Is running, but according to Elecraft I need to calibrate the radio again.

Are you by chance running any type of microham router while loading? This can be a problem.
