Bruce, I understand the frustration. Media links can be a problem even if you are moving the same data file or media folder to another location on the same computer, running the same software.
PAF likes the media to be in the same folder as the PAF data file. Then maybe globally relinking may work. Once you have the "relative links" to the media established, you can take your database and media (along with a copy of the installed PAF5 software folder) on a flash drive and run it on any current Windows computer without installing it on the host computer. It is great!
