Recieving an error when adding new address

[ActiveTuning]

Here's the error I'm getting when adding a new address for a customer:

 

1062 - Duplicate entry '1-582' for key 1

 

insert into address_book (entry_firstname, entry_lastname, entry_street_address, entry_postcode, entry_city, entry_country_id, entry_company, entry_zone_id, entry_state, customers_id) values ('John', 'Doe', '1 Main Street', '08540', 'Babaloo', '223', '', '41', '', '582')

 

[TEP STOP]

 

Any ideas how it can be fixed?
