I have just setup this plugin on an RSS feed.

When I click 'process' in the settings page it says it's done but "No new entries in your feed(s)." is all I get.

On the main autoblog page in the log I see this

• Processed: I have processed 0 of the 3 posts in the feed - http://nkp.clientcommunity.com.au/rss/newsletter/subitems/

This is the first time I have asked it to import from this feed, how do I force it to get started and import all of the posts that it sees in the feed?
