With Don's help and the K3 Utility Program Help file's troubleshooting section, I got the problem solved. I wasn't panicking but I felt much better after reloading the files updating the firmware to 5.67.
Turning off the P/S, unplugging the power to the radio and from the radio to the P3, and, probably most importantly, restarting the computer did the job.
Support from Don on a Saturday night is a big reason why I remain a loyal, delighted customer, with a K3S, P3/SVGA, K-Pod, and KPA1500. I've had Elecraft since 2009, which is the longest I've owned one radio (actually a K3 and then a K3S) since being first licensed in 1964.

Jim,
You apparently had some glitch in the computer to K3S communications during the process. Go to the Help file in K3 Utility and look at the instructions to "Force a Firmware Download" and follow the steps listed there.
Once you get to the actual firmware download, do not interrupt it The K3S will reset several times. If you get another computer glitch, repeat the process.
73,
Don W3FPR
