Hello, i bought the mw3 cd and can't install it. i tried to delete the files and install it with "C:\Program Files\Steam\Steam.exe" -install D:, and with restore a previous backup and choose cd to install, but it stucks at installed 0 / 14065 both times. I haven't fast internet connection and i don't wanna download the game from the steam because i'm not the only one who uses this internet. I tried to contact the activision support but it's always offline. Any help please?
