I can't access the site with http://www.moretolovebridal.ie/Pages/default.aspx. Also according to who.is your name servers are NOT pointed at 365:
http://who.is/whois/moretolovebridal.ie/
nserver: ns9.dnsireland.com
nserver: ns10.dnsireland.com
So unless you add an A record or change nameservers your site will never work. My guess is the domain is still pointed at another host and that cgi page is the index page there. After you verify, ping <domain>.sharepoint.com and see if you can get the ip address to add as an A record.
