troubleshoot my rss problem

Hi guys,

At PianoMedia.com my rss is not working. I just installed two days ago, and subscribed to my feed after making two posts. This worked fine and the posts came up. Then I decided to change the options so that the feed would only include excerpts. Now when I try to refresh the feed from any newsreader or even pull up the raw xml, I get nothing…

Who can help me figure it out?

Thanks…
