[Plugin: WordPress Move] Unsuccessful Domain Change

I built an updated site on a temporary url emarketingworld.co.uk and tried to then change the url to emmaobrien.com. the new url had previous pointed to an old site on a different server, so I also changed the A records of the domain to point to the new location. If I go to emarketingworld.co.uk the site will load the home page, but everything else is on emmaobrien.com and this does not resolve. If I go to emmaobrien.com this is not found.
Any suggestions much appreciated
