I bought Destiny legendary edition in Singapore recently, and when I brought it back to Vietnam to put in the codes it comes with, and it said: "The code you entered may not be correct or may no longer be valid. Please check your entry. (WC-40371-5)" What do I do about this problem? Is it a regional thing or something? I tried resetting my ps4 to put it in the Singapore timezone also, but that did nothing to help. The codes definitely didn't expire, so whats up? Thanks for your help!
