This XML file does not appear to have any style information associated with it..

This XML file does not appear to have any style information associated with it. The document tree is shown below.

What that means is that there's no stylesheet present on how to display the page. Stylesheets are only needed for when you want to view it in a browser.

Example of a XML document with a stylesheet:http://feeds.feedburner.com/viper007bondcom-rss2

It has the same kinda source as your feed, but it has a stylesheet that browsers use to display the page.

But as said above, it doesn't matter as no one needs to be viewing it in their browser. Feeds are meant for readers and such, not viewing in a browser. :)
