Thanks for the info. everyone.
David, what great advice! I am and will continue to enjoy this game. I have also downloaded many of the mods that others have created and am very appreciative of their work. I even read your earlier post about improvements for urban modelling in future versions of CM. I do not believe my question was out of line and found your comment to be gratuitous. I think BTS is appreciative of people like me who are eager to reward them for their creativity and originality by continuing to purchase their products.
Happy New Year!
