WE'RE SORRY, BUT THE WEB ADDRESS YOU'VE ENTERED IS NO LONGER AVAILABLE.

I'm instaling the new prestashop 1.6 ( normaly.. Craeting database removing instal folder ..) but when i acced to the administration page this message appears.. 

i tried this but it doesn't work :                                                                        SET FOREIGN_KEY_CHECKS=0;

UPDATE `core_store` SET store_id = 0 WHERE code='admin';

UPDATE `core_store_group` SET group_id = 0 WHERE name='Default';

UPDATE `core_website` SET website_id = 0 WHERE code='admin';

UPDATE `customer_group` SET customer_group_id = 0 WHERE customer_group_code='NOT LOGGED IN';

SET FOREIGN_KEY_CHECKS=1;

Please can someone help me to figure out how to solve this problem and thanks
