After using the totally non-obvious instructions to see that my preorder is confirmed, I still see no way to update my billing information, aside from the address. Since you tricked me into pre ordering 400 years before the game was released my card has long been shredded and expired... How can I go about that part?
Edit: I see someone else has the same issue:
Your best bet is to email firstname.lastname@example.org to have them (us) cancel the order and make a new one with a card that will be good until beta release.
So, when will that be? I need to make sure my card will still be good
