I came across your post searching for an answer to the exact same question. I only just realised my RSS no longer works, either at earleyedition.com/feed, or the original earleyedition.com/blog/feed
Which means my feedburner account has stopped updating new posts, without an actual feed to draw from.
Look forward to someone helping with this. Will keep looking in the meantime.

Because, probably, your feedburner ACCOUNT has the OLD (by now wrong) URL for your feeds. Did you change it?
I did change the URL before posting, and both URLs were returning my blog’s 404 page.
But it looks like it’s fixed itself today…
My rss stopped working too, and i didnt move a single thing…
