feedburner issues on the WP side

Hi,

Feedburner is not showing my feeds properly. When I went on the Google feedburner forum for help, I got this reply:

Feedburner is only showing what your original feed http://anniehearts.com/blog/feed/ has – which already has the error that makes the feed invalid. So really you need to ask WordPress support.

Here is my feed address:
http://feeds.feedburner.com/anniehearts/usgI

Can anybody help me decipher what is going on?

Thanks!
Annie
