Replies are not contained within a Topic

See here:

http://www.jkfweb.com/CADPORTAL/forum/

I was able to import the data, but if I open what I think is a topic it only shows the first post and no replies are in the topic.

Also in each category where you see the topics listed, it shows 0 replies even though there are replies.

The original forums I'm trying to import from are at www.ctrlaltdelpvp.com

Any help provided, would be greatly appreciated :)
