Hello. I just recently bought and installed an add-on from Travel by Train, a licensed partner of Dovetail. It is the same SD70 that was just released by that developer, just in Conrail and Norfolk Southern paint schemes. The engine is fantastic, and I have no complaints, but I have a bit of a phobia of installing unofficial third-party content (ruined my copy of MSTS) because of messing the simulator up. What I would like to know is, if I ever experience an issue, is there a way I can reset the game to factory settings and remove unofficial add-ons? I read in Dovetail's website that the uninstalling and reinstalling TS 2020 will reset it completely, but I am concerned that there would be an error if I did so. If I ever uninstall and reinstall TS, will the reinstalled game be like it was before I installed the add-on? The locomotive was installed by using the Utilities.exe tool in the railworks folder to install the .rwp file. Also, my copy of TS is the TS 2014 disc. Thank you for any answers and God Bless.
