Hi,
I thought this one had been resolved when the posts had stopped.
The only thing I can think of is that the problem coach is named differently on the CD than it is on the GWR Toddington download from the library on this site.
As I said previously, I had no problem with the activity, it ran straight away, but I have a downloaded version not the CD.
A solution I would suggest is to download Conbuilder Lite and substitute the offending coach for one in your collection, Conbuilder and RouteRiter are a must in my opinion for overcoming these sort of problems.
Hope you can sort it
Robert
