ERROR: Domain already exists

Hi,
whenever i try to add the domain www.thedentalworks.co.in to my account, i get a msg saying Domain already exists.
I might have created a trial account earlier when i heard of zoho to check how it works but i dont really remember. Now, i want to permanently link the domain to my email and im unable to do it. Can u please help me do so.
I have already followed the steps and addes the Cname on my DNS on godaddy

Attached is the link of my domain management    page which displays my domain name, expiration date and the existing DNS records on it. I have also sent the screenshot of this page on your mail support@zohomail.com .
Please help me recover my account linked with the domain. I read this solution on your forum.Cname
