[Elecraft] K3 - Firmware Download Issue

[Terry Schieler]

Today I decided to download the latest firmware for my P3. Perfect!  Then I
decided to download the latest K3 firmware.  When I ran K3 Utility all
seemed to go as usual.  When I clicked "Load firmware to K3" the LCD screen
on the K3 went out but I could still see MCU LD blinking in the display and
the red TX light continued to blink.  (The P3 was powered OFF).  

Upon investigation, I found that the K3 source folder that I was trying to
load from was empty.  The download had apparently snuck past me to a
different location.  Now, the power switch on the K3 will not turn it off.
When I remove power from the PS and then reconnect it, the K3 goes right
back to an unlit display with MCU LD flashing and the red TX LED blinking.

Any ideas on how I can get this K3 working again?
