If you have already installed WP:
Delete all files except wp-config.php from your site, extract the shaper .zip file and upload the contents of the "wordpress" folder to your site location.
Next, use your database manager (probably phpMyAdmin), and "drop" all tables in your WP database.
Finally, navigate to your site in your browser and follow the standard WP installation, making sure to select "install sample data" when prompted. Once that's done, just log in to your new site and make sure you update WP and all plugins.
