    Lightroom 5 catalog cannot be opened because another application already has it open?

    Singscience

      No matter what I do I cannot get Lightroom 5 to open because of this statement "The Lightroom catalog named "lightroom 5 Catalog" cannot be opened because another application already has it opened. Quit the other copy of Lightroom before trying to launch." My choices are "Choose a different catalog" "Continue" and "Exit."

      There are not other programs running. Problem still continued with Computer Security product uninstalled. There is no "different" catalog. Tried "open a new catalog, but any attempt to move files to a new catalog were met with failure. I am about to uninstall and reinstall, but I will lose my history of edits to my library. Anyone have advice.
