Can't download Podcast iTunes on Win7

I am a current listner of different types of podcasts. I can currently download podcasts all but 1.

The podcasts are from the The Daily App Show (Android Addition). When I try to download any podcast from this organisation all I get it the cloud symbol and to the left of the podcast list i get a ! in a circle refering to to an error "The URL" "http://feedproxy.google.com/~r/androidshow/~5Fjd6bc1T0Ea/lpa" could not be found on server, but I am able to click the cloud icon and watch/listern to the podcast.

This download problem has started since 03/2014. I have tried using a different podcast downloader and I am able to get them to download, but when using iTunes it will just refuse to download, I have un-subscribed re subscribed, deleted the iTunes libary file several times.

Is there something I am missing?
