Hi. I tried to install the CGL plugin, but when I try to run the SQL update from the admin, I get an error. Trying to run the SQL in MyPhpAdmin, I get the error:

SQL query: Documentation

INSERT INTO configuration (configuration_title, configuration_key, configuration_value,
configuration_description, configuration_group_id, sort_order,
last_modified, date_added, use_function, set_function)
VALUES ('Product Listing - Layout Style', 'PRODUCT_LISTING_LAYOUT_STYLE', 'rows',
'Select the layout style:<br />Each product can be listed in its own row (rows option)
or products can be listed in multiple columns per row (columns option)<br />
If customer control is enabled this sets the default style.', '8', '41', NULL,
now(), NULL, 'zen_cfg_select_option(array(\'rows\', \'columns\'),')

MySQL said: Documentation
#1062 - Duplicate entry 'PRODUCT_LISTING_LAYOUT_STYLE' for key 'unq_config_key_zen'


I'm not sure what to do about this. Tried it several times with the same result. Any ideas? Thanks.
