Well in other forum i usually visit, some people had problems with the activation of the game, they activated the game in origin but when they tried to activate with the same key inside the game they got an error. I think that's the reason why they are sending us new keys.
Missed DNF. It was in my shopping car and when i click in confirm order i got an error, "please contact support to make sure your order is complete", and now is unavailable. I hope it will be available later.
I just try to use a code and at first it says i cant use the coupon in that game and now i get the error "code was already used". I think the system are invalidating the coupons even if you get a error and dont buy.
