Addon Domains problem

[gooooogle]

I'm getting this problem when I'm trying to use the addon domains thing in cpanel.

Nameserver ips for memorycard.cc are: 69.57.152.2,69.57.152.141
Sorry, a DNS entry for memorycard.cc already exists, please delete it first

I'm really bummed as my domain now points to an empty web page with an advert on it.

Check to make sure it is not in any of your DNS zones..

The DNS names point to my host.

In WHM you can edit your DNS zones and such, make sure the domain is not listed in there from previous accounts.
