Account management

Hello,
I am trying to join my company's CRM group, which is subsrcribed to a payware version of ZOHO CRM. I previously created by own CRM "company" as a free account, but managed meanwhile to delete myself out of it. Our ZOHO admin does not manage to add me in to CRM; he is getting the message that I already have an account, though this is not true any more for CRM. Please help me, thank you!
