Nice day,

Hello XenoX,

You may start BeamNG.drive manually, either by using Steam (if you have bought it there) or by starting the .exe from where the game is saved on your pc.

Thanks, Da_Lightbar,
But I talk about beamMP drive and no beamNG drive

After you started the BeamMP application, you’ll need to start BeamNG.
