The game is completely in English (like the gamecard says) but some of my menues are in German langue. I use a German Win7 OS so that is probably the reason for thsi but is there a way to force this game to only use ONE language? This mix is a bit confusing.

Edit: If you don't want this add the parameter "-language english" to the shortcut (just like the one you already have if you'd want to launche the game in spanish).
