First off, do this. In your config.php, turn the mod_rewrite to false and make sure that it works that way. If that works, we can try getting your URL’s working again, just make sure that it is working. If you have phpmyadmin access on your server you can check the bb_posts table to see if the actual posts are there (I am sure they are) as they are showing the topics and the number of posts still. It seems like a permalinks problem and starting by turning them off will be the quickest way to test that.
