The Hero's Path

I wanted to play this map, but I encountered the following problem: I download the map, move it to the Maps folder, but "Heroes" doesn't recognize the map. It will probably be the same with other downloaded maps. I have already reinstalled Heroes several times from different sources. And the most interesting thing is that the standard Heroes from one source without the Russian language pack 3.1 recognized this map. It is impossible to play it without the Russian language pack, and when I installed it, the map disappeared again. I tried to find an answer to this question on the forum, but I didn't find it. Help me.
