Feed Wrangler won’t save feeds

I just upgraded to WP 2.6 and added a new plugin – Feed Wrangler which is supposed to allow you to syndicate feed to locations like googlebase, Trulia and Zillow. It’s uploaded and opened as plugin and admin panel looks fine. When I go to save a “Slug” (feed name) it says it saves it but then as soon as you leave the screen and come back it is gone. If you save more than one feed at the same session it will overwrite the first one and then never save the second. I want to use with the new Great Real Estate Plugin which is great but this would make it wonderful! Thanks in advance for any assistance.
