Problem Adding My Own Domain!!!

[teamicon]

I've tried adding my own domain (teamicon.biz) but the system is saying an error message (domain owned by another user).\

I already pointed my domain with the nameservers ns1.x10hosting.com and ns2.x10hosting.com.

What seems to be the problem???

Thanks for any help!
Edit:
This is the error message.
(Error from park wrapper: teamicon.biz is owned by another user.)

You need to for 36 hours to let the DNS designation promulgate. You could try again later. Hope this helps.

Are you doing an add-on domain or parked?
