"An attempt was made to access an unnamed file past its end"
I'm having the same problem, after re-installing S&T 2008, but only with my largest, newest map. It opens others, that I don't need any more, just fine. The one it won't open has the addresses and years marked of most of our ancestors,
so it's quite valuable to us, and would take a year or two to do over! I'll try renaming it, but I'm not optimistic.
