Hiya tixilite,
As I can't post in your thread I decided to help you via PM. To do what you want to do, all you need to do is login on this page:
http://x10hosting.com/
You will then be directed to your account settings, look the for the content box titled "Account Details" check the box "Check if using your own domain name" and then input your .co.cc (e.g. - abc123.co.cc) domain name!
As long as your name servers are pointing to ns1.x10hosting.com and ns2.x10hosting.com then you should be now able to access your cpanel from "abc123.co.cc/cpanel"
Hope this helps you mate!!! (make sure you post in your help thread quoting this by me so others having the same problem can sort it out themselves!)
