After having removed the Trainz installation and then reinstalling it, I find much of the items working, however several scenarios in the Cornish Mainline do not work still. Two in particular - the trip to Falmouth and the Cornish Mainline. What happens is the scenario loads in. The AI does some train movements which flag AI trains as having passed a signal at red. Before I can do anything the controls for my train are removed and later the screen fades to black. Later a display comes up stating I failed the scenario. Is anyone aware of any issues or can they tell me to fix this issue. It makes no sense, other than the AI red flags are being treated as my own.
