I was able to get this working with one of my feeds, so here are a couple things you might want to check.
First, be sure that Private Addresses are enabled in Remember The Milk. You can find this option under Settings > General. This ensures your Atom feed is public and can be read by other applications.
Also, be sure you're viewing the completed items for your list when you copy the Atom feed URL. This will get you updates on completed tasks rather than incomplete tasks.
When you paste the URL, be sure that it has the very long, random token value (just like the example URL in the recipe) and that this token value is not truncated or altered.
Hope this helps!
