    Lightroom 5 suddenly doesn't recognize my serial number.... Help?

    BarnettPhotography

      I get this message when I try to open lightroom on my computer (I've had lightroom 5 installed on this computer for a full year, and not the cloud version):

       

      "The serial number you entered is invalid. Please try again."

       

      It won't ever work. It is the correct serial number.

       

      Help is appreciated!
