Pretty much what sohamb03 said. It's not your account, the domain just won't clean up like it should, making it impossible for me to finish removing it so you can add it again. Krydos might be able to clean it up manually.
It has to be removed from the DNS cluster for you to add it as an add-on. However since it is not being removed due to a server error, it has to be fixed by Krydos. Please wait until then.
I think you didn't get what I mean. I have a recent backup of my site when it was in tommy server. Now after I created ricky account, I uploaded the backup (full backup) to my new ricky account. Now I only can restore partiality. But I read it somewhere that root admins can restore full backups. I want to restore the full backup. That's what I am requesting for. Thanks for your response.
