Look at the directory that you have downloaded the files from elecraft 
into. You should have at least

DTBL0008.HEX
HDSP0158.HEX
hmcu0178.hex
TBOOT7.HEX

Make sure the K3 utility is set to use this directory.

Check the version of the K3 utility that you are using. Is should be at 
least 1.0.12.7, and the current version is 1.1.2.28.

I am just guessing but the error message sounds as though it is not 
finding the right files.

The K3 utility figures out the correct baud rate, changes it to 38,400 
for the download and then changes it back. So you don't need to do anything.

You can save configurations if you are going to play with menu 
parameters and you want to be able to get back to a known setup.
