I'm sorry for what may just be a noobish question, but I've got the disk which comes with the first three expansions for the Xbox. The system downloaded those three expansions along with the updates when I installed the game, so I've got those. The other expansions I bought two days later, and I've registered the all the codes here on the SE account website. I assumed they would just download when I next began playing, but they did not. All I get is a notice message telling me that 'You do not have the expansions downloaded, you will not be able to play them.' or something to that tune. I can still play the game, it starts up after the notice message, but I can't play Wings of the Goddess, Abyssea, etc.

My question is this: how do you download the expansions through PlayOnline for the Xbox 360?
