First, run this query

Code:
SELECT configuration_group_id
FROM configuration_group
WHERE configuration_group_title= 'Google Analytics Configuration';
If no row is returned, just delete the two "DELETE" lines from the beginning of googleanalytics.sql:

Code:
DELETE FROM configuration WHERE configuration_group_id = @t4;
DELETE FROM configuration_group WHERE configuration_group_id = @t4;
Otherwise, if it does return a number, you'll then need to run the following queries to see what may be deleted. Replace <number> with what was returned above

Code:
SELECT * FROM configuration WHERE configuration_group_id = <number>;
SELECT * FROM configuration_group WHERE configuration_group_id = <number>;
If any rows are returned by those two queries, you'll need to back up those lines before running the googleanalytics.sql script.
