Have you deleted preferences recently? Lightroom looks like it's created a new default empty catalog, so I suspect your real catalog has a different name. Perhaps look in some of those folders for a .lrcat file with a recent 'Date Modified'.
Thank you Sean for the response. I looked thru and I don't see any additional .lrcat files. The empty one has the most up to date modification date but also has the original date of install. So this must be the 'correct' one? Its just empty?
Your help and additional input would be help from anyone who might be able to help would be much appreciated.
In Lightroom, see if there are catalogs listed under File->Open Recent and open those.
If that doesn't work, don't search your hard disk by looking yourself; have your operating system search all hard disks for *.lrcat files
