Rollins Pass route

I previously had the freeware Rollins Pass route loaded and working in Open Rails. Then I downloaded and installed an update to add the doors to the Moffat Tunnel. That stopped the route working.
I have just re-downloaded the route and installed it again, minus that update. RouteRiter found no errors, but now OR won't "see" the route.
As far as I can see all the normal files needed are present.
Any thoughts?

Update. Although I gaily installed the route in a folder called Rollins Pass, since that is how the route is referred to, it is actually called D&SL Moffat Road by OR.
So now working.
