Kathy I was using a small Sony laptop which wasn't powerful enough to process all these pictures, which was part of the problem. I did switch to an Powerbook and after learning the operating system I am pretty happy with it. Never had a problem with Lightroom but I download directly from my Nikons. Lightroom runs circles around Elements. It's a true pro program.
The other lesson I learned is never do major updates to anything when your at sea. Wait till you get home if all goes wrong it will be easy to fix. I just load the security updates.
