Please go to the main menu of the game and check whether the version number starts with 3.0. If so, you have to install the two patches which are published for the game. You have to install the 3.1 patch first, before installing the 3.2 patch. The version number in the main menu will change to 3.2 after correct installation.
Please note: these patches are only compatible with the German retail box and is only for Windows.
