Why can't I open my Stata .dta file?

The new version of Stata is not backwards compatible; in other words Stata 6 cannot open Stata 7 (the current version of Stata available at the Statlab) or Stata/Se files. However, the updated version of StatTrasfer (also available on Statlab computers) can convert files across all three file versions: 6, 7, and SE. If using Stata 6 at home, remember to use StatTransfer before leaving the lab.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
