HoMM3 HD is a mod (add-on) for the game Heroes of Might and Magic 3.

Oelm, couldn't you at least write the password for the archive in a private message?

As it is, I don't have the time. I would work on this save, but not to save your game (because of the time it would take), but for research, to determine the causes, so that we can take them into account in HDMod.
