Did you "overwrite" anything by chance, Don? You MIGHT want to try the CHECK feature in the project utilities. The Events option checks place links to make sure they are associated in the Place library. If the place is not found, the place is restored and given a "Missing Place no. nn" name. The "nn" is then replaced by the place record number. You can Edit the place name in the Individual Record window to change "Missing Place" to the correct place name. When you save (or F9) it will give you a message is this the same as ... and everything with the place number will change (I think). It's been awhile since I did it.
If there are further problems, we may have to dig for more answers.
