BeamMP Launcher - Launches singleplayer beamNG

Not sure what I’ve done wrong but every time I click the desktop icon ‘BeamMP-Launcher’ is starts up fine and all but then launches the normal singleplayer BeamNG from steam? (in-game shows no option of multiplayer.)

any help with this would be greatly appreciated.

Did you click play and then in the top right hand corner where you can select freeroam you should have an option for multiplayer.
