Hello and Welcome to x10hosting.
Just so we can get an idea here, I have a few questions to ask.
1. Have you signed up with our hosting service (
http://www.x10hosting.com/hosting ) ?
2. If so, have you received the confirmation e-mail ( this would have all information relating to your hosting account )
3. If not, this is how you go about setting up a Cpanel name and account.
