So when I try to start TruckersMP and click on ETS I get this error message: http://prntscr.com/kzfx1z
But when I start singleplayer I have all the new trailers and the new features, so this means that I have the new game version installed.
I deinstalled the game and TruckersMP a couple of times but it didn't change anything.
I also don't have a Beta installed: http://prntscr.com/kzfzcl
I tried also installing with some of the betas but it also did not help
