I've also had a problem with redeem my limited edition code, because I couldn't sign into gamesas website. Now it is work and I entered my limited edition code last night. Then I launched my Crysis 2 game and I logged in and I saw my upgrades thanks to my limited edition type of the game. I gat a promotion from my 9 rank to 10. I got the new version of Scar and a hologram to it. BUT!
BUT when I entered the session, my stats changed to 9 rank without new scar and hologram! When I left the session, my rank was 9 ! And I had blocked hologram and new Scar.
I turned off the game and launched it once again.And what has happened? EVERYTHING THE SAME! I got a message that I have unlocked new content of limited edition and bla bla bla etc...
Please help, because I can say, that I cannot play with limited edition content.
Yours,
