cooperjamieson.com is directing to GoDaddy now. Did you recently change your domain's name servers?
When a domain is registered or altered, there is a process called propagation, where information about the domain name is passed to internet service providers all over the world. This process can take up to 72 hours (though usually much less). During that time, your domain may go to its old location, and you may also receive a warning message in your browser about "redirect errors."
If you still have trouble viewing the site after 48 hours have passed, please try clearing your browser's cache.
If that doesn't work, try clearing your local DNS cache: https://support.opendns.com/entries/26336865-Clearing-the-DNS-Cache-on-Computers-Servers-and-Web-Browsers
