You need to change the table names to have zen_ in front of them...

i.e.

Code:
INSERT INTO `zen_configuration_group` VALUES (NULL, 'Zen Lightbox', 'Configure Zen Lightbox settings', '0', '1');

UPDATE `zen_configuration_group` SET `sort_order` = LAST_INSERT_ID() WHERE `configuration_group_id` = LAST_INSERT_ID();

SELECT @cgi := `configuration_group_id` FROM `zen_configuration_group` WHERE `configuration_group_title` = 'Zen Lightbox';

INSERT INTO `zen_configuration`... etc.
