XMLRPC and Ecto

I’m running WordPress 1.5 and posting with ecto on the Mac, but I’ve run into some problems with XMLRPC. It does give me an error when I try refreshing to recieve all the posts that have not been posted with ecto.

I get the following error:
Could not parse response for “metaWeblog.getRecentPosts”. Please check the console log for more information
