    I have Lightroom 4.2 which isn't opening in Windows 7. A message comes up saying it's already open in another application. I've tried shutting down and restarting; still not opening.

      I have Lightroom 4.2 which isn't opening in Windows 7. A message comes up saying it's already open in another application; I can't see that it is. I've been using this successfully for 2 years now! I've tried shutting down and restarting; still not opening.
