Your problem is a confirmed Windows 2000 problem with how the town AVI files are read. No one running Windows 2000 has access to this buildings. FOrtunately, there is a fix that will take a little work on your part. Go to the following site and convert your town AVI files to an uncompress AVI. Note that this will make them huge, but you will be able to play the game.
