RSS “feed does not validate”

I just started my first wordpress blog, and I’m having difficulties with the RSS feed. When I try to subscribe with google reader, or to enter it into feedburner or any other validator, it tells me there’s nothing there. Is there something I need to do to activate it? Or is something broken?

I’ve searched google and browsed through these forums but haven’t found anything that helps me.

I’d be much obliged for any advice!

Thanks in advance!
