UBB.threads PHP Forum Software Community Forums UBB.classic UBB.classic 6 Support 5.47d to 6.0 beta 7 upgrade problem

First, I really like UBB 6.0!!!

I do have one problem. Not all of my threads made it from 5.47d to 6.0
http://www.dalantech.com/cgi-bin/ultimatebb.cgi

Even though the initial page shows topics and posts, most of the sections are empty now.

How can I recover the old posts?

If I can't recover the old posts then how do I make the topic and post counts acurate?
