hi, i hope someone is gonna answer this,
2 days ago i buy crysis 2 limited edition in the USA, ( Im from Spain), and when i tried to redeem my code of limited edition it said that was wrong, i already put the code exactly but i cant get the gifts, always i get the wrong code warning...
My Network acc is from Spain

USA game/Spanish account, there's your problem.

is there any thing i can do?

Nope, my guess is you're out of luck here. These codes are region specific. If it's any consolation, you're not missing much. The hologram attachment is kind of cool, but the extra XP just means you're locked out of the noob class in multiplayer sooner, which may not even be a good thing, and the weapon skin is totally pointless.

The only thing you will miss out on that you cannot get is a digital (well, it sais urban) Scar skin, and a Platinum dog tag surround,

you can easily get to level 5
easily unlock the hologram.

so i wouldn't worry

I ve bought it from GAMESTATION.CO.UK from EUROPE and my account is from US. I went to EA home support page, pvssyd with a guy there and in the middle of the chat he sent an US code for the limited edition and blocked the one i have from the europe zone...and it worked. Go to the EA SUPPORT PAGE. I didn′t want to make another account and it was solved! Im from Argentina
