Error on module

Hello,

I installed the "og_multiple_mandatory_groups_by_role" module.

I've an error when I go to admin/og/og_multiple_mandatory_groups_by_role/groups:

* user warning: Unknown column 'o.selective' in 'where clause' query: SELECT n.nid, n.title, o.* FROM node n INNER JOIN og o ON n.nid = o.nid WHERE (o.selective = 3 OR o.selective = 0) ORDER BY n.title in /var/www/drupal/modules/og_multiple_mandatory_groups_by_role/og_multiple_mandatory_groups_by_role.module on line 645.
* warning: Invalid argument supplied for foreach() in /var/www/drupal/includes/form.inc on line 1417.

Any help would be appreciated!
Thanks!!!
