I have both Trainz 10 and Trainz 12. I thought that trainz 12 would be backward compatible to at least Trainz 10. I have routes and sessions on trainz 10 that seem to play okay on trainz 10. Try to copy Via CDP to trainz 12 I might get the route to load but it is totally unrecognizeable as compared to trainz 10 I fire up the CMP that comes with trainz 10 look at the installed route in question and it shows that there are 4 misssing dependencies 3 of which are supposedly on the DLS I look at the same route with the CMP that comes with trainz 12 and the number of missing dependencies is in the thousands How can this be? All I want to do is work on a route that works fairly well on trainz 10 in trainz 12
