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

Thank you for your responses. My problems were resolved with the superpack_rus.
Some auxiliary showmessages also pop up when loading the game from saves. And today, there was a situation where the game crashed due to the internet connection, so I had to load from a save that wasn't created by the person who initially started the game. Since then, passwords are no longer requested:D maybe I didn't load it correctly?)
There was also a crash when creating a map with the computer as an opponent, but it hasn't happened again.
