Thread:Extension talk:ArticleFeedback/update.php does not create the proper tables/reply

Had a similar issue. Initially happened when viewing Special:ArticleFeedback (I enabled the dashboard in the extension settings first.) Checked the MySQL database, the specified table did not exist although 6 others did. Running update.php again produced the error reported above. Better installation instructions would be appreciated.
