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

I have the following problem: I installed the original Heroes 3 SOD (English version, a clean version not from Бука - the American version), then installed the HD mod, and now I can't type in English; instead, I get hieroglyphs...
P.S. I've tried switching the keyboard layout and using Ctrl+Alt to type, but I still get hieroglyphs.
