1062 - Duplicate entry '1' for key 'PRIMARY' after importing old database

[gws76]

Website with the issue www(dot)sullivanvitamins(dot)com Note the website is down for maintenance.

My hosting company upgraded their PHP on Sunday and when I went to my website on Monday I got many depricated errors as my shopping cart was outdated. I have installed the latest version of Zen Cart 1.5.1 but I'm having trouble accessing store data whether it be categories/products on the main page or in the admin customers/orders. I've tried importing my sql from my backup I did on Monday but get the following errors listed below.

Error

SQL query:

--
-- Dumping data for table `address_format`
--
INSERT INTO `address_format` ( `address_format_id` , `address_format` , `address_summary` )
VALUES ( 1, '$firstname $lastname$cr$streets$cr$city, $postcode$cr$statecomma$country', '$city / $country' ) , ( 2, '$firstname $lastname$cr$streets$cr$city, $state $postcode$cr$country', '$city, $state / $country' ) , ( 3, '$firstname $lastname$cr$streets$cr$city$cr$postcode - $statecomma$country', '$state / $country' ) , ( 4, '$firstname $lastname$cr$streets$cr$city ($postcode)$cr$country', '$postcode / $country' ) , ( 5, '$firstname $lastname$cr$streets$cr$postcode $city$cr$country', '$city / $country' ) , ( 6, '$firstname $lastname$cr$streets$cr$city$cr$state$cr$postcode$cr$country', '$postcode / $country' ) ;

Then I tried importing in phpMYADMIN the same file again and I got this error afterwards. What I'm I doing wrong?

Error
