THAT'S what I needed, guys. Thanks.
I was leery of using the repair option as I wasn't sure if I would have lost all my imported stuff, and that wouldn't have been good. Too much time trying to get it all working to have to install and tweak it all again.
THIS time I back up not only the original panel, gauges, and so forth-files, I now also back up the Sim Objects file. Must've been vapor locked to have forgotten to back THAT one up!
Thanks for the help. You folks r the best in the business! 8-)
