nrelate is not cycling my blog posts. It displays the same ones below each post.

Well, just like the thread title says. I installed nrelate a few days ago. My site isn’t live yet, but I have about 15 sample posts up, each one with a different title. But the same five posts are displayed in the widget, in the exact same order. When I refresh the page, nothing changes except for the pre-loaded images.

Can you please help me with this? Thanks!
