Feedburner problems

I updated wordpress to version 2.8.5 the other day and ever since then my rss feed won’t work with Feedburner. I am running the FeedSmith plug-in. Any help with this would be greatly appreciated.

My site: redrisingblog.com
RSS Feed: http://redrisingblog.com/?feed=rss2
Feedburner Feed: http://feeds.feedburner.com/RedRising

This is the message that Feedburner is giving me:

FeedBurner had trouble retrieving your Source Feed: http://redrisingblog.com/?feed=rss2

The error message is:

Error on line 1: The element type “meta” must be terminated by the matching end-tag “</meta>”.

Thanks.
