I'm sure I'm doing something stupid, but here's the deal. I purchased Season 10A of South Park after the season was over. All 7 episodes downloaded fine. After the third episode of Season 10B I purchased the season. The first 3 episodes downloaded as expected. As far as I can tell, the fourth episode is available, but it doesn't download. I'm under the impression that once new episodes become available, they automagically download (or as the help says, they are automatically added to my download queue). Is there something I can do to trigger the download?
