Feedburner Trouble

Hi, my site is http://billybrew.com

My feedburner url is http://feeds.feedburner.com/billybrew, which is
linked to the RSS icon on the site, but when you click the RSS button
in the address bar it goes to this address which doesn’t exist:
http://feeds.feedburner.com/BillyBrewFeed

How can I change this address to the correct feed address?

I am using WordPress 2.9.1 and the Feedburner FeedSmith plugin.

Thanks!
