Black screen in itunes store after updating to itunes 7.3.1.3

I am running Windows XP, and just updated to itunes 7.3.1.3 after getting a few podcast download errors. Now that I've updated, when I navigate into the itunes store and try to look at items, when I click on an item (for example a podcast), when the screen for that podcast loads, for a split-second I see the screen as it is supposed to look (graphic, list of episodes, etc.), but then all that is replaced by a black screen. When I move the mouse around on that black screen, I see where different areas are clickable, so the content is there, I just can't see any graphics. The latest update that caused this issue updated both itunes and quicktime. Solution?
