It turns out my Wifi was acting up and I couldn't get the full download so I couldn't install the program. I did it from a computer that was hardwired and that worked.
I have installed PSE 14 now and I tried converting a TEST catalogue and it converted properly. I will back-up my REAL catalogue and then try it. (There are 15,000 photos in it so I don't want it not to work!)
Thanks for your help.
