The 2K Sports Forums are abuzz with comments from purchasers of the PC edition of NBA 2K9 who have discovered the game was shipped without the CD keys required to activate their installation. This page on the 2K Sports Website offers a workaround, saying: "If you've had issues installing NBA 2K9 for the PC, please know that a solution is now in place. This solution will be downloaded automatically and seamlessly when you install your game, and no Product Key is required." They have contact information for anyone who cannot get this to work. Thanks Voodoo Extreme.
