My host had a massive server failure last week so I've switched to a new provider and am restoring my blog from a backup I made a while back...
I installed the latest build of WordPress (2.0.2) and imported the tables in PHPmyAdmin. so far so good. The posts and comments all seem to be there. However, when I am in the admin section under Manage->Posts I get the following message in the column for comments:
WordPress database error: [Unknown column 'comment_count' in 'field list']
SELECT comment_count FROM wp2_posts WHERE ID = '526'
