Joomla!®Plug

I think I'm missing something here, but I don't know what. I just installed JoomlaCloner on my website. I filled in all the settings, including the cron page. After saving I went back to the cron page and found my configuration listed - with an "execute cron" link beside it. So I clicked the link. Here is what I got:

Starting /homepages/6/d122126874/htdocs/FontlabBiz/administrator/components/com_cloner/cloner.cron.php
Using configs/DailyBak.php as configuration file
Access Denied for ip 190.33.255.65!

Two questions:
1. Why did I get this and what to do about it.
2. How do I schedule a cron job?

Thanks,
Ted
