It's good to know I'm not the only one having problems getting everything downloaded. I'm on broadband and it's been hours of disconnects.
It was the same way when I first bought the game; I tell everyone who buys the game I think Square Enix does it to weed out the weak and unworthy. If you have the patience to sit through a few days of disconnect notices, you somehow deserve to play.
Then again it installs and downloads with any hitch for some people, so I guess they're trying to tell me something. /em whimpers.
