    lrcat.lock can't be found, catalog can't be opened


      The catalog's message when trying to open is: 'The Lightroom catalog cannot be opened because another application already has it opened. Quit the other copy of Lightroom before trying to launch'. I read deleting of the lock file might help. Can't find the lock file. Searched anywhere. Please help!
