I discovered the latest update of Calibre is causing some windows 10 users to have Calibre not launch. Reinstalling an older version fixes that issue, so I though I would experiment since I had little to lose.I got it fixed.

1. Installed an older version.
2. Manually moved all books (in their folders) into the "new" library folder.
3.Moved the current "metadata" and the" metadata_db_prefs_backup.json" files out of the "new" library file into a random folder.
4. Left the "metadata_pre_restore" file in the new library folder.
5. Then renamed it "metadata".
6.Ran Restore Database from Library Management and it worked.

All books and preferences were restored.
Thanks for your help.
