lost previous sessions on upgrade

  • I upgraded to SessionRestore 1.6.1 today. An alert popped up saying that SessionRestore needed more privileges. I went to System Preferences and checked the box to activate SessionRestore. Now in Safari, all the previous sessions are gone. I would like to get that data back. I do have computer backups. Can I get the previous SessionRestore data from a backup? Where is that data located?
