[SOLVED] "Recent Posts" widget not showing up

I'm creating a new site using ATA v3.6.4 and WordPress v3.0.3 www.dehumidifierreviews.us

So far I've only created 3 pages; "About", "Contact Us" and "Privacy Policy". No Posts yet

I created a new "Categories" widget on the Right Sidebar which overrided the default WP widgets ( "Recent Posts", "Blog Roll" and "Meta")

Next I created a new "Recent Posts" widget, but it does not show up on the site. (although it is present at: Appearance » Widgets » Right Sidebar)

Then I created a new "Text" widget, which shows up on the site.

Question; Why is the "Recent Posts" widget not showing up? Is it because I have not created any posts yet?

2nd Question; Is it possible to maintain the Default "Recent Posts" widget and then add other widgets like "Category" and "Text" without overriding it?
