I am using Itunes 22.214.171.124 on a Dell Latitude D531 laptop running Windows XP Home. In the middle of a session using Itunes a few days ago I noticed that in my Itunes library the NPR Fresh Air podcast had been renamed as "Podcast Error" and all of the subscribed podcast entries (in my library) that had not been downloaded to my computer's hard drive had disappeared. The only podcasts that are listed are those that I've downloaded.
I have several other podcasts that I subscribe to; they appear normal in my itunes library.
I've subscribed to the NPR Fresh Air podcast since some time in 2009 and have been manually selecting ones to download to my computer's hard drive during all that time (through numerous updates to Itunes).
It is likely that I could fix this by following the advice in "http://support.apple.com/kb/HT2562" which is entitled "Podcasts playlist in iTunes is empty" (or similar such advice that can be found on the Internet). My question is twofold: What caused this to happen? Is there a more subtle fix for the problem?
