[Elecraft] KX3: Trouble downloading new firmware

[len at ka7ftp.com]

I thought I might update the firmware in my KX3 this afternoon.  I'm
currently running 2.38

 

I have my KX3 connected to my computer and running the KX3 utility.  The
communication is working fine with the radio.  When I click on the "Copy New
Files from Elecraft" button I get this:

 

Opening connection to ftp.elecraft.com

Opening connection to ftp.elecraft.com

Connected to Elecraft server

Please be patient, this takes a few seconds

InternetFindNextFile completed with error 0x00000006: The handle is invalid.

 

I closed the KX3 Utility and retried, same result.  I've updated the
firmware several times before without issue.  I can get to the web Elecraft
site, as well as the ftp site, so it is not a connectivity issue.
Suggestions?
