I received a number of messages asking if people needed to download the map for the game. Yes. Greece Stain is not included in the initial dominions install, so you need to obtain it. The map is given in
this thread, which is also linked on the first post.
All the map confusion came from the .map file that I uploaded to the server, which contains information that only the server needs. You don't have to worry about that; you just need the image file for Greece Stain (GreeceStain.rgb) to be in your maps directory.
