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

Please advise on a solution: we are trying to connect via Grengor. I have versions 2.98 and 3.0 of the HD mod. When attempting to generate a map, it displays: "Unable to create Random_map in the data directory." What should I do? There are maps in the randommaps folder.
