What's wrong with my feed?

It started yesterday, and continues until now.. I don't know what's the reason, but from yesterday the blog's feed is down. If you try to visit my Atom feed on your browser you'll get an error page containing the text "Invalid request URI". And my Feedburner version shows up an error page saying that my feed is making a "clunking" sound. That's normal of course, if we consider that Feedburner generates the burned version from blogger's original Atom feed.
I've searched Blogger Help to see if I can find a workaround to the problem, with no results. So I sended them an email and now wait patiently.. :(
If you had or are having the same problem, I'd like to hear from you. Especially if you know how to fix it ;)
