I have the same issue. The game only shows up on the secure.square-enix.com site, however on na.square-enix.com it does not. Also the new client says: No valid or active service account is available to play FINAL FANTASY XIV: A Realm Reborn.

Yet when looking at the account I originally registered 1.0 with it clearly says I have an active service account (and a legacy character in beta)...am I missing something? Do we have to buy the game again if we don't qualify for legacy? My understanding is legacy gave you bonuses like EA, but you didn't need legacy to play your 1.0 account in 2.0.
