If I'm not mistaken, you should be able to log into your account from the client, just the play button will not pop up. So somewhere around the middle of the update maintenance you should be able to get the update. If this doesn't work. sadly you'll have to wait. I say this cause in FFXI you can log into you game account and update the game without an active account. The play button is just grayed out saying no active account characters available or some such. I could be wrong cause it's been like forever since I played XI, but it's worth a check since the worst tht can happen is it just will not update right?
