GMzH: I was able to install the program (with a couple of error messages) and to start a new game from the demo but no scenery appeared. I got some overlay windows on a black screen. (The loading screens look alright.)

Drastically reducing the video options shifted the black to a reddish-greyshade picture on which orange house symbols started to move after a short while. Enhancing brightness didn't change anything.

Any suggestions about how to get a visible landscape would be appreciated...
