Harley Quinn’s Revenge has invalid serial key

Harley Quinn’s Revenge has invalid serial key
I purchased Batman Arkham City: Harley Quinn’s Revenge game DVD from the local game store. I got a serial key along with it and other details in the manual. I installed the game and the part where it asks the Serial key, I inserted the code that came with the game. But the game shows, ‘Invalid Key’ error and fails to install. The game which I purchased is original and the serial key also came along with the packet. Can anybody tell me what can be the problem?

Re: Harley Quinn’s Revenge has invalid serial key
I know what can be your problem can be. My friend brought Batman Arkham City: Harley Quinn’s Revenge and in the serial key he got, there was alphabet ‘G’. The serial key was printed in such a small font with a thick ink that ‘G’ looked like ‘6’. So if this is same case in your serial key, try using ‘G’ instead of ‘6’ or vice versa. If still the serial key doesn’t work, then you can send the picture of the pack along with the close up picture of your serial key. It would be better if you send the photo of the receipt along with it too. The developers will send you a different serial key to activate your game.
