you will need to connect to the database directly using PHPMyADMIN or another MySQL GUI Tool and run the following query:
DELETE FROM `ps4_contents` WHERE `ContentID` = 2;
DELETE FROM `ps4_contents` WHERE `ContentID` = 15;
INSERT INTO `ps4_contents` (`ContentID`,`ContentGroup`,`ContentRefID`,`ContentValue`,`ContentDate`,`ContentUserID`,`ContentPageName`,`ContentPageSetParentID`,`ContentPageSetOrder`,`ContentType`,`ContentParentGroup`)
VALUES
(2, 'Home Page', 'Site Message', '<h1><span class="ps_highlight">Your Store</span> Message Goes Here!</h1>', '2009-08-25 17:55:08', 0, NULL, NULL, NULL, 'TXT', NULL),
(15, 'Popular Pod', 'Header', 'Most Popular', '2010-01-14 13:44:04', 0, NULL, NULL, NULL, 'TXT', 'Home Page');
