I had the same problem as both of you! My gamestop code failed to work, and I even called gamestop. They told me to continue to try and use the code, and I did... Now... I Have error code 80023156. I was confused, so I gave sony a call and I told them my error code and they didn't have a clue what it was. So yeah... Im guessing that we have been locked out temporarily for too many incorrect codes. (Gamestop should reimburses us, wahh. - With what I don't know=p)
Anyways, we'll see what happens tommorow... I'll post back here with updates. I was sooo stoked to play MAG beta, or at least download it today. They stole it from me! =p
Keep us updated on your luck. I don't mind having to give gamestop a call and chirp them out a bit. =P (This is the reason I pre-ordered from gamestop, as opposed to some place in canada... where I live... =p)
They owe us some justice! =p
Today i pre-ordered Uncharted 2 at Futureshop and i had a promotional code for a special theme. At first it says that it was incorrect or expired. I tried to case sensitive the code but nothing happened. And them i told myself maybe some letters are printed incorrectly soo i tried a different letter and bang!! an error occur 80023156. Can anyone tell me what is this error code and i am from Quebec Canada.
I called yesterday about my MAG code, it gave me the same error, she said it means the code is not active yet, but i think you should call Sony, tell them it does'nt work, they might give you a new code. One quick question, did you try to enter the code many times before you got this error?
