Error Modifying Domain

[Osiris19]

For my Hosting account, I wanted to change my domain name from my co.cc to an .x10hosting.com domain because I want to use another co.cc name because I have changed the direction of my website. The original name was neutra-tuts.co.cc, but when I try to change it to osirisdesigns.x10hosting.com I get an error message.
Action Status: Error
Information: A change to your hosting account's primary domain.
Result: A system error occurred while processing this action.

Error Code: F3F45C7A
