Mapping issues

I am setting up a website http://www.salongenevieve.co.uk but hosting it on http://www.marshalldigital.co.uk. WP is mapped to Salongenevieve, however, when you click on a link on the page, the web address changes back to http://www.marshalldigital.co.uk/salongen/?page_id=22 rather than http://www.salongenevieve.co.uk/about/ . Any idea how I can make sure all pages stay as http://www.salongenevieve.co.uk/pagename?

Many thanks in advance!
