Hi Murtkesr, I had faced similar issue and i followed these steps. Since you have already completed checking file in steam and Truckersmp Can you check Your Steam Privacy Settings: Open Steam and go to Edit Profile > Privacy Settings. Under My Profile, ensure it is set to Public. Look for Game Details and make sure it is also set to Public. Once you've updated the settings, check if the DLC is visible in TruckersMP.
