I had the correct version of 1.37 to run TruckersMP. I went to play single player and ATS updated to 1.38 open beta without my permission. I have it set to update only when I launch it now when i go to downgrade back to 1.37 open beta the correct version for TruckersMP is not showing in the list now on steam.. Can someone help me and figure out how i can get the correct version back for TruckersMP please and thank you
