Hi Steve,The place to start is to double check and make sure you have all of the current libraries installed and properly activated. As for the smoke, check in your effects folder for a file called 'fx_VentSteam", which is the effect that defines the smoke.
I have been trying for two days to get all of the scenery working. Right now I cant get he medical facilities working or the Alaska power project.This has become pretty tedious.Tom
