Hello. I bought some DLC on Steam and installed them in my game. In the offline game runs with the DLC normally. Well my problem is this. I open the Euro Truck Simulator 2 Multiplayer and the following message appears (shown in the screenshot). The image is in Portuguese but probably you will know what it is.
NOTE: I activated all DLCs purchased from Steam.
