We have a P3P compact privacy policy so IE should work in the High privacy setting. If that fails set it to allow cookies for www.designbuilder.co.uk or set Privacy to Medium High. Other browsers also have cookie blocking options. For example in Firefox use Tools -> Options... -> Privacy -> Cookies to control the cookie settings.
