I uninstalled the game and deleted only the game folder found in /steamapps/common, then I reinstalled and downloaded again.
The error is that the game simply does not start, when i click on Play in steam I get for some seconds the mouse pointer as loading circle and nothing more. As I wrote, I checked the windows task manager and sometimes I found a “train fever” process running in background, but that’s all.

thx for your help 🙂
