If you wish to change your domain, this can be done under 'hosting > modify service' in the account panel (
http://x10hosting.com/control/login.php).
Also, it appears your domain is redirecting to itself:
Redirect Loop
Redirection limit for this URL exceeded. Unable to load the requested page. This may be caused by cookies that are blocked.
The browser has stopped trying to retrieve the requested item. The site is
redirecting the request in a way that will never complete.
* Have you disabled or blocked cookies required by this site?
* NOTE: If accepting the site's cookies does not resolve the problem, it is probably a server configuration issue and not your computer.
This is most likely caused if you have two domains set to redirect to each other, which is what it looks like at the moment. You need to remove the redirect for the domain you want to use under cpanel, then change to that domain through the account panel.
