I had copied the entire directory structure to zip disk (and hard disk), including all library files.
I'm trying to determine which specific files hold marriage links and dates, which files hold location information, and which hold my evidence links. Hopefully, then I can swap out the appropriate files.
I have even tried reinstalling the program, and then swapping out the library and projects folders. I was still presented with several messages regarding corrupted files.
From now on, I will also create *.sqz files as well. Thanks for your suggestion.
