Although I was unable to exactly determine the source of failure, by using the Restore K3 Configuration button and use a previously saved file, brought the receiver back to life- thankfully! Tweaking those tmp connectors helped as well.
Wish I was able to get a better picture on what happened- like so many things in life, sometimes you reboot and move on ..... Thanks for all the helpful suggestions here!
