If you have an original copy of the map (still at 768 kb), try opening the file with a text editor
Right Click > Open With > Notepad (or similar)

There you can see all the content of the map in text form, try doing a search for any names of objects that you know of, like 'PlayerStartArea' for example, to see if that is still there

Or look in virtual store.
If someone can tell him where virtual store is i would be happy, because i don't know right now! :p
