Hmm... I've encountered a similar problem... check the file size... if it's around 1 KB, it probably means the game is installed in a directory with a Russian name... for example, I had it installed in E/Games/Heroes... I reinstalled Windows and the game, but this time I installed it directly on the drive, i.e., I removed the "Games" folder, and now everything is fine.
That's strange. My game is installed in the standard location: C/Program Files/Heroes5
And so on.
But the editor is glitching. The maps are saved with a size of 22 bytes:confused: Why?:smile45:
