PS3 Battlefield 3 multiplayer voucher?

I have an american copy of BF3, trying to play it on a ps3 that has a South African PSN account tied to it.



When I try to redeem the online voucher to play multiplayer, I get a bogus error that reads:



" this voucher is no longer valid"



It was bought from a legit store and stil sealed. Not the first time I've had the same error when trying to redeem vouchers.



How the hell do I redeem these freaking codes? Please help.PS3 Battlefield 3 multiplayer voucher?

Try swapping it for a South African copy.
