Our Podcast won't download

Hi,

We have a podcast that has been added to iTunes called Truskill Games Podcast, however, some iOS users are having trouble downloading the podcast. The podcast is hosted on our website http://www.truskillgames.com/Podcast/All/Default.aspx

No other podcast player other than the inbuilt one in iOS is having an issue. It can stream without any issues, but the same person may not be able to download it.

Please can someone help?

Thanks

Hardeep
