Battlefield 4 BETA Medal of Honor Warfighter

So I was looking online and to get access to the beta with the limited edition you need to be a registered owner of the game, that statement confuses me was I suppose to resister the game online. I was looking at the back of the box and it says beta entry and details avaliable at www.medalofhonor.com/bf4-beta but I didn't notice it at the time so does that mean I am out of luck or what. I pre- ordered the limited edition so I did get the zero dark thirty map pack
So can someone clear it it up for me PS3 btw
