backlash

I played this game during Thanksgiving I think? They had a free weekend trial. I just bought the game from Steam over the Christmas sale. Have a friend who wants to play online. I thought MP was integrated into the game, so I'm just finding out you have to use the mod. Thanks so much for the great work making this happen, but I'm obviously having some issues. I made an account here, linked my Steam account, downloaded the mod launcher, but when I launch it says I am using version 1.3.1 when I'm obviously using the 1.36.x latest version. I think the free trial gave me an Arizona add-on map and possibly some extra trucks. Should I disable all the extra content? Possibly delete everything and reinstall? Not sure what the issue is exactly since I haven't added any mods. Any insight would be greatly appreciated.
