Hi, Can anyone provide an explanation for this?

I tried to access a website on my pc (evanscycles.com) and the following message came up:

org.xml.sax.SAXException: The content of elements must consist of well-formed character data or markup

I thought it was a website issue so thought I'd come back later, but it turns out the website shows fine on my other 2 comps but not on this one. All are running IE7 and all have the latest windows updates...any ideas?!

Thanks

Ian
