If the fix that I proposed works in that manor, it won't take long for you to get your code. If they wipe that part of the database that stores the already sent psn codes and have you use the preorder site again for the correct region, you should get a new, good code. What I don't understand and why they haven't done this yet. While it sounds like a good solution, I don't know the how their database is setup and if SE or Sony is the one that manages it, so I can't really say it's that simple.
