Hi Donna, Restore your most recent backup and check this family. Also do a Check/Repair on the restored backup. If all is well,use the restored version and update it with any additions (usually the highest RIN and MRIN numbers).
If THAT backup is corrupted, restore the backup previous to it, and so forth until you get back before the problem occurred. (At each step check the highest RIN to see how many people are in the database, to see how many are being lost as you go back to ealier backups.)
Or email me a copy of the paf file and I will run it through PAF Insight, which has a better Repair function, and send it back. Obviously some file pointers are scrambled, and PAF Insight seems to be much better at repairing these than PAF.
