Sherman Hill Missing Track Textures

[FHRob]

I'm trying to run a scenario from the workshop "EWS 66 on Sherman Hill." When I load the scenario, it almost immediately becomes a slide show.

I cloned the scenario using RW tools, and converted it to a standard scenario. When I opened the scenario using the TS build function, the tracks show "texture missing."

What's my next step here? The missing textures occur in the Cheyenne yard.

Thanks,

Rob
