I'm still trying @Adam. Reseted my password and still Google doesnt allow me to enter with that mail. It says this:

We are sorry, but you do not have access to this service. Please log in to your Admin Console to enable this service. Learn more

Can you try doing this in a browser other than the one you normally use?

I can't log it on gmail, even in godaddy.com. Restablished my password and still, it's not problem of the password, i dont know where to login with the mail contact@fiendworks.es @Adam . Do you know where i can login the mail? Every page I try to log in says that they're sending a email verification but i cant log anywhere.

What is the message about sending verification that you are getting?

Google doesn't allow me to enter the mail because i need to verify it in an Admin console. But i cant. Do you know where i have to log in @Adam?

Yes, the Admin console URL follows this format:

https://admin.google.com/INSERTDOMAINNAME/

Replace "INSERTDOMAINNAME" with your domain name and it should load for you.

Thank you @Adam, it works!

That's great!
