BATTLEFIELD 3 PREMIUM EDITION ORIGIN INSTALLATION ERROR.

So I bought BF3 premium edition the other day from a video game store. I starts the installation and I was asked to give the code that is inside the box.I gave the code and origin verified it as genuine but when I proceed a message popped-up saying that I can't install the game.My system specs are really good and when I tried to do it again by typing the code origin said that it has already been used (by me). So there is nothing I can do.. Can anyone help? :S
