CAPTCHA FOR ZENCART - SQL error upon install

[rodent042]

I just upgraded from 1.39g to 1.39h and have run into an issue.

I did a complete fresh install, not an upgrade. All other plugins went in without a hitch. This mod worked in the previous version flawlessly.

The code:

SET SQL_MODE="NO_AUTO_VALUE_ON_ZERO";





INSERT INTO `configuration` VALUES ('', 'Capctha security code', 'ACCOUNT_CAPTCHA', 'true', 'Enables captcha on customer registration form', 5, 4, '2009-03-27 11:05:16', '0001-01-01 00:00:00', NULL, 'zen_cfg_select_option(array(''true'', ''false''),');

The result:

1062 Duplicate entry '0' for key 1
in:
[INSERT INTO configuration VALUES ('', 'Capctha security code', 'ACCOUNT_CAPTCHA', 'true', 'Enables captcha on customer registration form', 5, 4, '2009-03-27 11:05:16', '0001-01-01 00:00:00', NULL, 'zen_cfg_select_option(array(''true'', ''false''),');]
If you were entering information, press the BACK button in your browser and re-check the information you had entered to be sure you left no blank fields.

I currently know just enough to get myself into trouble lol. I think I understand that there is an issue with auto-incrementing and it should be an easy fix but I am a beginner and afraid to just hack at it as this is a live store.

Can someone help the poor ol' rodent out?
