Seems like your missing or misplaced the STEVO BUILDINGS "The file "Sceneryobjects\Stevo Buildings\LCC Cottage Estate Repaint\vic_terraced_2.sco" could not be loaded!" thats all i can minus the bus issues which im not 100% sure if it would cause an issue but the main issue is its not loading the Steve Buildings. Hopefully try re-installing them or moving them to the correct directory. Hope this sorts the issue out.
Thanks. That was the problem. Just reinstalled the STEVO Buildings and now everything works.
