just made a quick map. I imported a shp file containing only 1 point marking the location of a sewer plant. I go to edit that shape file, but adding a text field with the name of the plant, so i can create an automatic label. Looks great until I close arcmap, and then try to re-open that map. I get the above message. Any way to fix it, or more importantly, how do i keep it from happening? Any help will be greatly appreciated.
