If you look in the right column, you will notice that the subscription model has changed. I am now using FeedBurner to host feeds which gives the extra benefit of allowing for email notification of new posts.
Someone asked for this awhile ago and now it makes sense to make the change. Until recently I was not aware that FeedBurner had been bought out by Google. It is amazing how much they have now.
I tested it out and everything looks fine. Hope things go as smoothly for you.
