Thanks for your help
I thank those who helped me with my initial frustrations with the PCGS registry. To me, it wasn't intuitive what to do and how to edit files. @alaura22 showed me one step that ended torrents of swearing from me and I'm grateful. Others helped as well, and that has enabled me to enjoy the registry. Mine was a classic case of not reading the instructions before assembly. That reminds me, are there any clear instructions for problems on this site. (redfaced) I haven't checked.
