RSS ticker issue

Hi,

I’m embedding a RSS ticker onto a site pointing to a blog and it’s posts. At first I used RSS pump (http://www.rsspump.com/) but later discovered this embedded Google Ads also.

So I used an alternative from Dynamic Drive
http://www.dynamicdrive.com/dynamicindex17/rsstickerajax/index.htm

I works fine referencing the smaple RSS feeds, but when I submit my own into the code ‘http://www.example.com/blog/?feed=rss2’

I get the following error
“Error fetching remote RSS feed!
Sorry: It’s not possible to reach RSS file http://www.example.com/blog/?feed=rss2″

but cleraly the RSS feed is found here. So I’m wondering is there a location for an XML file of your posts so that I can try this.

Any help would be great. Been wrecking my head all day over this.
