i was abel to log in to the multiplayer game but now i can´t play because when i want to load an existing profile or make a brand new profile, the game says "The saved game you are trying to download using the DLC (downloadable content) that is currently lacking. The lacking contents are: DLC - Going East! It is impossible to proceed with that save game without the proper DLC. " what does that mean and what do i have to do to fix that?! I already have DLC - going east but do i have to buy it once again to make it work with the MP game?!
