ITunes Store says all content for Apple ID has been downloaded when it hasn't.

Question

I have multiple Season Passes for TV shows. When I got to Store: Check for available content after receiving the e-mail that the episode[s] are available, I get a message saying that there are no purchases to download for this Apple ID.
When I go to the store, I can find my pre-paid purchases and download them from there. It's quite annoying to have to manually download all my Season Passes.
Why would my purchases not be available for download using the Check for content menu option but available in the store proper?
Thanks in advance for any advice or suggestions.

Answer 1

I wanted to follow up here because the problem turned out to be a problem with iTunes billing, something that other people may experience. Specifically, turns out the account was blocked because of a billing dispute, and that dispute was caused by the iTunes store's practice of not billing some sales at the time they take place (in this case, days or weeks afterwards). This led me to believe a charge was incorrect and having the credit card company block it, which in turn led to the account being disabled (without explanation).
The iTunes store needs to improve their billing practices so that charges are reflected promptly in customers' accounts. Otherwise problems like this will occur.
