What is my Zoho CRM username? (problems integrating with Zopim)

Ok, I was under this belief that my Zoho CRM username was just the e-mail address I use to login but for some odd reason, it is not working when i try to integrate with Zopim.  I can't find where my username is so I would welcome help.
