I downloaded it once but the file got partly corrupted (I didnt know that was possible

) and all I got was graphic files.
I think I will download it again...
I am allready using impassable units but I want a terrain to use so that the player will actually see the passes (impassables are invissible to allow for grouped mountain ranges) and also the passes will give a trade bonus (and have a movement cost of 1 1/3 I think).
