Forums Plugin - no "new" and not showing on page

Hi,
I just upgraded WPMU 2.8.6 to 2.9.1.1. I'm using Multi-DB 2.9. I'm now updating my plugins. I updated the Forums Plugin 1.5.1 to 1.6.2. I renamed the two databases (wp_topics and wp_post) per install.txt.

The "New" link and "Click here to add new forum" are not showing in Admin - Forums tab. My site Forums tab says "No topics to display..." I previously had one test topic and one test post.

I created a new topic and post on the page. They display fine.

What to do?
Thanks,
ChuckS
