Paypal Express

I would like to add paypal express and i get this error after saving:

“Database error: Duplicate entry ‘12-ES’ for key 1 (1062)

Invalid query: INSERT INTO cscart_payment_descriptions (payment, description, payment_id, lang_code) VALUES (‘Paypal Express’, ‘Paypal Express’, ‘12’, ‘ES’)”

whats that?

You’ve already got data in that field,

I suggest that you open phpmyadmin or any other sql review tool and clear the entries then try again
