I entered the code from the battlefield 4 box to update my copy to my new ps4 . It didn't update. Ps4 says cannot read ps3 disk. It will not let me re enter code says it has already been redeem.
I am having the same problem and I AM PISSED!
The PS4 just kept loading after i entered the redeem code and never stopped. then it reset itself out to the menu screen. when i went back in NO redeemed code, NO battlefield 4 and an error saying code has been used already when i try to re enter the code WTF?????
