Cant download podcast
Having a little trouble getting the latest edition of a podcast from iTunes. iTunes was downloading the podcast automatically earlier today, when an error message alerted me that the download was being stopped because I was out of space on the drive I keep my music on. I clicked OK, and freed up some space on the drive. Now, however, I seem to be unable to finish downloading the podcast. It's showing up faded out under the list with the "Get" button next to it, but clicking on "Get" only seems to make it start to download for a split second before it stops and an exclamation point appears to the left of the file.
I'm trying to figure out why it's doing this; perhaps iTunes thinks it already downloaded the file so it won't do it again? Is there any way I can get it to download? I've tried deleting it from the list, finding it in the iTunes store and downloading if from there, unsubscribing from the podcast and attempting to download it, unsubscribing/resubscribing and then downloading, but I get the same result every time with the exclamation mark and the file grayed out.
The RSS feed for the podcast actually only keeps the latest one, so if I can't figure out how to fix this by Monday I won't be able to get the episode at all. Anyone have any ideas?
