registration code already been used?

[maTyaR]

but you clearly state that you are not sure if the thing in your thread will work with PS3, i have the registration code right here in my hands it came with my physical cppy of the game, but the code says already been used when i try to use it

Your issue seems serious, o_o. If you've purchased it directly, you'll have to contact their support and determine which account is using your product code and when (or it could just be a system error).
