User warning: unknown column

Drupal 4.7.2
PHP 4.4.2
MySQL 5.0.18-standard-log

Installed 4.7.0 Drupal, upgraded to 4.7.1 and then to 4.7.2. Installed event module, and when I created a test event I got:

    * user warning: Unknown column 'pid' in 'field list' query: UPDATE node SET pid = 0, stops = 'a:0:{}' WHERE nid = 1 in /home/...path.../MYUSER/MYSITE.COM/...path.../includes/database.mysql.inc on line 120.
