Does it give you the "Place Missing from Library" message at all? Each place in the Place Library has it's own internal record number. When a place is added to an event, a link from the event to that place record number is made. If that place is missing because you deleted it from a different project, you deleted it from the Place library, or you overwrote the Library files, it needs to be restored. To restore the missing place -- in your case to rename place zero -- backup your Project and Library files first. Choose Utilities/Project/Check. Select all options in Project group except maybe Add Birth/Death events, Gedcom Tags and Streamline Research text ... then click Repair (Okay checks for missing places but does not restore them). The knowledge base has more,I think on the Missing Place no. nn and things like that. Check it for further, as I don't have that stuff in front of me at the moment. Anyway, you need to overwrite the Missing Place. If it has just been overwritten by another place, you might be able to do a search/replace, depending upon what version of UFT you are using.
