News Sitemap Error

Keep getting this error on my news site map.
“post_google_news.xml does not have any item. You can fix this easily by excluding any post types / terms you do not use in Sitemap Generator tab within your admin area. If you still see this error, consider checking the module that generates this sitemap (post_google_news.php).”

I’ve tried to include all I can and Google webmaster tools keeps giving me a 404 error to.

Am I misunderstanding something in the setup or settings?
