Hi Kurt,
I don't have a Microkeyer but I distinctly remember some list traffic
some time back warning, "Don't try to update firmware through a
Microkeyer." If you look at the block diagram on the Microham web site,
the CAT interface comes from the internal CPU in the Microkeyer.
Assuming my memory is at least partially still intact, I believe that
was the problem, the firmware in the Microkeyer interferes with the K3
handshaking with the K3 Utility during FW loads.
What are your connectors? The K3 is a 2 row female DB9 if I remember
right [it's buried back in the non-wireless part of my station and its
very dark back there]
You can probably get a USB-RS232 adapter locally cheaper than paying
shipping costs. The Elecraft adapter I have uses the Prolific chip set
and runs fine. Some say the FTDI chip set is more reliable.

Thanks to everybody for your advice.
But my problem still not solved, because I am communicating with the K3
via my Microkeyer2.
