Super Admin Email?

I can't figure out who the super admin is for my account - what email I used. Now I can't get in to set up my email. I can login with erica@lightlabstudios.com, but don't have access to the control panel. I know my URL is already linked. I've tried resets with a few of my emails. They're not linked to this account and it won't let me sign up with URL (lightlabstudios.com) because it's already registered. Can you tell me what the super admin email is so I can get in? I'm wondering if there's a mix up from my having used the super admin email on another Zoho account (a client).

Thanks
