RSS feed not being found

Hi

I was wondering if anyone could help, I keep getting this message from Safari about my RSS feed and I’m assuming it’s going to be something simular in IE:

Safari can’t open the page “feed://www.jupperpeep.com/jadedeye/feed/”. The error is: “The feed could not be loaded because the content is not in a known feed format.” (PubSub:2) Please choose Safari > Report Bugs to Apple, note the error number, and describe what you did before you saw this message.

Does anyone know what I would need to do to sort this out?

Thanks
Jean-Philippe
