Hi all,,,,I am answering my own question here,,
The reason is,,I copied the cdp initially on to a flash drive and then after I reinstalled trainz I installed the route again and
then took out the flash drive,,of course that's where trainz was looking for it.
So I copied it off the flash drive on to my C drive and installed it again from there.
Hey presto its there to work on again.
I guess my quote underneath is true sometimes.
Thanks
Len
