I am trying to figure out why are third party routes won't start otherwise any of DoveTail Games Routes Addon are working in my program of Train Simulator 2018? When I click " Start " on Steam then pick one of the third route to run on Train simulator 2018 but crash to Steam start up page after complete loading. Then I decided to see if one of DTG Route Addon to run and it's working with no problem after start up. Any idea with third party routes? John
I would suggest running a integrity check of the game sounds like a file is missing causing the issues you are having.
I forgot all about this and have to remember next time to do this to run a integrity check of the game. I just finished with this and surprised to see that 4,081 files failed to validate and will be reacquired. All is good now. John
