Error from park wrapper: phinassi.info is already configured

[phinassi54]

Hi, when I try to add on a domain in Cpanel, the following error show up:
Error from park wrapper: phinassi.info is already configured.

here is the solution:
remove the domain.com entries from:
/var/named/domain.com.db
/etc/httpd/conf/httpd.conf
/var/cpanel/users/username remove (dd) related entries to domain,
/etc/userdomains
/etc/localdomains
vim /etc/named.conf remove (dd) related entries to domain
remove dns entry in whm
run /scripts/updateuserdomains

I have no permission to do this, administrator, could you help me to do it?
thanks.
