    Why won't Lightroom open?

    Ashley K Franklin

      In trying to open Lightroom, I get the pop up box telling me that 'Lightroom cannot use the catalog named "Lightroom Catalog" because it is not writable and cannot be opened.'  It then says: 'This could be caused by incorrect permissions or because another Lightroom application is using the catalog.  You may try to correct the problem or you may select a different catalog.'  I usually re-start the PC and it then opens, sometimes it takes two or three re-starts.  However, I have re-started six times and I get the same message.  On one forum I went to, the advice is 'delete the .lock file'.  I searched the PC and I do have a .lock.file.  Should I delete it?  Is this the solution?
