If I use feedburner, I get messages like this: but your computer or network may be sending automated queries

If I don't, I get gibberish: <?xml version="1.0" encoding="utf-8"?>
<!-- generator="Joomla! - Open Source Content Management" -->
<?xml-stylesheet href="http://jaefilmcorp.org/components/com_easypaypalbuttons/assets/easypaypalbuttons.css" type="text/css"?>
<rss version="2.0" xmlns:atom="http://www.w3.org/2005/Atom">

I can't find any resolution on this issue in the documentation.
