Post Navigation Fix

Hello,
The post navigation on my blog, are not pointing to the ‘previous’ and ‘next’ posts. Instead one is pointing to my blogs’ static page, and the other to another section of my site (arcade games). You can see what I am referring to here. http://www.corzac-games.com/super-smash-bros-wii-us-8-player-smash-is-super-crazy/

How can I change the text, and have them point to the previous and next posts? thank you.
