Problem solved! Creative Cloud indicated that there was an upgrade to LRC, and I clicked the dialog box. For some strange reason Adobe downloaded Lightroom, changed the name to LRC, and left me a mess. Adobe helped uninstall whatever was installed, and reinstall LRC, and all is well, the sun will come up tomorrow, the birds will sing, and I'm a happy camper. Thanks for all of your suggestions as I can sleep soundly tonight!
