I have followed the instructions and entered this code for the limited edition content several times and all I keep getting is 'code not found'. What do I have to do to get this to work. Also although I have loaded this onto what is supposed to be a gaming laptop the game itself only shows up in the programmes list for removeing the game. It is not on the desk top or in the startup menu list and I have no idea why. Can anbody help me out with these problems?
