Corporate Slave Installation Error

I installed WP 2.5.1 with the Corporate Slave theme, and it’s install / configuration issues are turning me into a slave! I installed the plugins and wrote two posts that I want to appear always at the top of my home page. The page loads, but I get “404 Page Not Found” text in both post positions.

Can someone please take a look at it, and tell me where to look for the error?

Here’s the link:

Thanks in Advance.
