NHF – new heroes for Heroes V 3.1.

So, I deleted both versions of the game, manually cleaned the registry. I installed a clean version 3.1, put the mod in the data folder. I launched it, the map loaded, it's the player's turn, and a message pops up: "This version of the game does not support the NHF file. Current game version 3.1" That's it, I give up, I don't know what to do anymore.

Incorrectly quoted! "This version of the game is not supported by the NHF mod. Current game version 3.1" I have this version installed, what more does it want?

I figured it out, I have version 3.0. I downloaded three games, and they all have version 3.0, although the description says 3.1
