Installation problems.

Do you have problems launching a new DLC? To get started, check that you have the DLC badge on the top left in the country selection menu. If not, then you need to update the game on Steam. If it is, go to your library and find the line with the DLC. If it says "Installed - no", then remove and tick the DLC, and then wait until it is installed. If this does not help you, then write in the comments under this post, we will help you.
