Question about product key.

[Black_Wing]

Assuming they don't expire.....might as well try. Not like any harm will come of it - worst is you get an error message. Not familar with PS3/4 platform in this case - but most PPC's generally have an expiration date of some kind....and are locked to the account they are redeemed on.

PS3 code is specific to PS3, you had to participate in the "upgrade" campaign to get your key transferred to a PS4 key.
