Your best bet is to just try & see if you can register a new site with .co.cc.
They might have you blocked now though, possibly by IP address or by your personal details that you gave on registration.
Try & see. If you are blocked, you could try & apologise to them & see if they will allow you back. Of course, there are ways of disguising your IP address, but that's against their TOS so I wouldn't recommend it!
I don't know about the status of your account with x10. Is it still active, or has it been banned too? If so, it may only be temporary. Check in your Account Panel to View Suspensions.
And of course
Don't Do It Again. Stay within the TOS next time!
P.S. .co.cc and/or x10hosting did you a favour by terminating your account. If the movie companies etc decided to go after you for distributing illegal copies of their products, you could be facing large legal fees.
