I updated my Euro Truck Simulator 2 on Steam and the multiplayer launcher like 1 hour before. Then I tried to launch ETS 2 in multiplayer but it crashed with topic "Game crashed - FATAL ERROR" and message "An application fatal error! Do you want to send crash.log file to developers?". I sent it a few times and also tried to start multiplayer after deinstalling the launcher and reinstall the multiplayer launcher but it still don't work.
