I am having similar trouble with this as well , although things are loading to the right folders , I still get error messages , the game loads ok if I ignore the errors but tunnels (subway) I can only see the signals and nothing else .All the sounds and functions are working fine , but I keep overrunning stops cos I cant see , its certainly a challenge to "drive blind " slowing and stopping for amber or red signals lol .Also any train cab loads ok , its just the structures I cant see .
