Funny story:
As I posted before, I was able to register my LE code after trying a dozen times. Then when I loaded the game, a messaged popped up saying that I obtained the bonus experience points and unlocks. So I happily configured my character's weapons and all. However, when I joined a game, it said I was level 1.
Looged out and back in, said I was level 5, reconfigure equipment and join a game and I was back at level 1.
Frustrated, I used EA's live chat support. They provided me with another code and I haven't been able to register that one.
But they did give me a $20 voucher code to redeem on EA's store.

I entered my LE redeem code and received this "Your purchase transaction was received. The status of your transaction is shown below: , and below is a blank window with a home button that when clicked sends me back to the screen where you enter your redeem code. I added the hyphens in the code but still get no response ??? Anyone have any ideas.

Same problem here as well. My game was pre-purchased on Steam and I've got 2 codes. One is the LE Game Code (Serial) and the other is for "Crysis 2 Bundle". I've logged in to multiplayer using my serial number successfully, however when I attempt to redeem these codes on this site it doesn't work.
Another issue is when I successfully enter multiplayer menu of the game using my serial number I can't connect to any matches because I get a message saying my "serial is currently in use" ? ? ? ? Any help would be appreciated, much thanks.

HEY EVERYONE LISTEN UP!! I FOUND THE SOLUTION!!!

Follow this link i found at EA website, follow the instructions.

Clear ur cookies and re-login to ur gamesas.com WITH YOUR EMAIL then try redeeming the code.. it works for me..

I was able to activate my LE copy by using IE instead of Firefox. Kept getting the same error messages. Once I used IE, it accepted it. Now my problem, since this is my first time purchasing a LE, how do I use the bonus features?

Is not working... Again.

Problem fixed:
Here's what to do. Take the game and get your money back. On the grounds that you can't redeem code and no direct X 11 support as advertised!

Mine is activated but I don't receive any bonuses

I put the code on gamesas.com/limitededition while installing no problem with that. But when i try to log into the game it says my code is not valid. That is crap...Plus i have no awnsers form mods or anything im stuck with a 70$ game that wont open...im pissed.

I redeemed the code successfully yesterday (received an email saying so, and the purchase info is in my account), but I still don't have the bonuses in the game. My in-game account and my gamesas.com account aren't linked at all.

Someone PLEASE help.
