[Plugin: WP-O-Matic] Does not auto fetch.

I installed the plugin and ran the install, added the following cron to my Go Daddy account:

*/20 * * * * /usr/bin/curl http://stablesystemsnow.com/wp-content/plugins/wp-o-matic/cron.php code=4404c14c

I also set the WP-O-Matic timer to 0 0 30 hopeful it would run each 30 minutes.

The manual fetch works just fine, but its not automating.
