The Hero's Path

I've had a licensed copy since the beginning (I still have the original disc from way back in 2008). I downloaded patch 3.1, but it doesn't recognize the map. I decided to download a different version from Rutracker – the English version – and it recognized the map, but it's unplayable. I installed the Russian language pack, and it stopped recognizing the map again. I downloaded the Gold Edition, and it's the same problem.
