1. Extract into an empty folder USING 7ZIP!!!
2. Run GreenLuma.exe inside the folder. Make sure you choose offline mode.
3. Choose Train Simulator 2013 in the Steam Library and Play! GreenLuma is a cracked Steam client. It is best to create a bogus Steam account and use that account instead of this one. Make sure you choose offline mode every time you start GreenLuma.exe. A readme is also included. like so everybody can see how to play it!!!
