iTMS ... er, lost my copy of Lost

Well, that's what I get for trying out a brand new feature of the iTMS a few paltry hours after the announcement. I clicked on Lost, deciding to spend $1.99 to download last week's episode, just so I could see how this new goodness works in the iTMS. It took about 32 minutes to download and at the very last minute, when I thought it was going to announce that it was complete, I got the following error:

And then iTunes crashed. The file is nowhere in my Library and now whenever I try to Check for Purchased Music... underneath the Advanced menu in iTunes, I get a "iTMS temporarily unavailable." Grr...
Update: I got it finally. Cool...
