I need some help here please. I cannot seem to get rid of this:

Warning: constant() [function.constant]: Couldn't find constant MODULE_ORDER_TOTAL_INSURANCE_ZONE_2 in xxxx/includes/modules/order_total/ot_insurance.php on line 43

I read where another member had the same thing and they uninstalled the sql patch and re-installed. I do not know how to uninstall the patch.
Can someone let me know what I need to put in the sql patch area to uninstall the table from the database so I can have the error above removed from the admin side.

Thanks
