I just got my permanent code

[Merxion]

Where do I add it at? I went to http://na.square-enix.com/us/gamereg/ site then attempted to add a code of XXXXXX - 000 - XXXXXX - 000 (6 letters + 3 digits + 6 letters + 3 digits) when I hit check code it told me it was invalid. Any ideas?

Same. I too got one. Came up invalid. Can't put it into the Mogstation either obviously.
