Family Historian 3 is now very out of date but if you have it
installed on your computer it should still work. Why are you
unable to access it?
If you purchase and install V7 on the same computer your data
will be preserved, but as a precaution you should make a full
backup of your V3 Gedcom file and any linked media files first.
(You should always keep backups anyway, in case of computer
failure). There have been very many changes since version 3 so it
will be a steep learning curve.
