MSTS problems Options

[smokeytc]

Hi all.. all of a sudden, I am having major problems with Train Sim. Routes that I have been using for years (Pokey, Cape Cod, Gallup, Clovis) and some new ones (Scenic 2, ACN) are giving me trouble. I can make activities for all, but while loading "setting up simulation", I keep getting error messages such "can't load xxx.s shape files. OR - it will load to "loading world content" and then I get error "can't add car xxxxx.wag (UID123456) to world".
Yesterday I defragged my HD, reloaded the clone from my backup HD, and still getting the same errors. Am about to reinstall complete Train Simulator, but thought I would ask in here first, and see if anyone has any thoughts on this prob, or a fix???? Any and all help will be appreciated
