Feedburner Feed Replacement Plugin Help

Hi guys.

I’m trying to get a plugin that will let me redirect subscribers to Feedburner.

I got this plugin:

http://orderedlist.com/articles/wordpress-feedburner-plugin/

The plugin basically creates a new URL for my feed so I can point Feedburner towards it. This way I won’t have to make any changes to the core of WordPress.

Well I’ve activated the plugin, the permalinks are redirecting and all. However the URL that the plugin creates gives a 404. And since it’s a 404 I can’t get Feedburner to point to it.

This is the URL:

http://ganai.com/feedburner_882266/

Do you guys have any idea what might be the cause of this?
