It appears to be a problem with the new iOS 7 update. I have researched it on the Apple forums and others are having problems with their podcasts downloading. I will try some of Apple's suggestions in troubleshooting the problem.
I just tried it and couldn't replicate any issue with accessing the episodes from iTunes. Is this every episode or just one? I tried several episodes and couldn't replicate the error. You may also want to view the iTunes support for help with podcasts: www.apple.com/support/itunes/itunes-u/
I have tried multiple times to listen to Sparkpeople Radio on iTunes. I have subscribed to the podcasts and download an episode only to get an error message telling me the episode is temporarily unavailable. Is anyone else having this problem? I am downloading them just like I would any other podcast.
