Anno 2070 Key Mapping (Anno 2070)

Actually, this is the problem, after reassigning the keys in the game settings, they get confused when you re-enter the game and you have to set them up every time (keyboard layout), which is incredibly crap. They are reset to "Standard Settings", does anyone know how to fix this? or at least suggest where this file is stored with standard settings in order to edit it? Thanks in advance.
