Ultimate Facebook – Can't get comments to show

I’ve purchased Ultimate Facebook. I can’t get the Comments to show up on my site. Check out the Home Page of http://www.MarinNostalgia.org. What am I doing wrong?

I’ve stuck a Widgetized plug in on left. Nothing is appearing! I’ve toggled the options in every combination and it doesn’t make a difference. Plus, when I imported the comments nothing happened.

PLEASE HELP!”
