[Plugin: Yet Another Related Posts Plugin] Moved my blog and no YARPP info shows up

I was having technical problems with my blog and I had to start fresh on a new server at a new host. I created a new WP install from scratch on the new server. Then I exported the XML file from my old blog and imported it into that new blog. Then I installed the YARPP plugin and activated it.

None of the YARPP information is there on the new blog. It says “no related posts” on each of my posts. I suspect this information was somewhere in the SQL database, which I didn’t transfer over because it was the cause of my technical problems.

Is there anything I can do to restore the YARPP info from the old blog?
