sunderbear noted that EAs Command & Conquer 3 shipped missing the last digit of the CD Key. He writes "EA's brightest minds have put their synapses into overdrive in order to whip up a comical work-around. 'There is currently a work-around that may allow you to bypass this issue. Since you have the first 19 characters of the code already, you can basically try guessing the last character,' said a note on EA's customer support site. Yes, they're serious. 'To do this, simply enter your existing code, and then for the last character, try the letters A-Z, and then the numbers 0-9. You should eventually get the right combination, and be able to play the game.'"
It appears that the helpful hint has been purged.
