How to solve "The username which you have entered belongs to a different deployment/region"?

Hi,

I need to register the domain www.fortalezaferroeaco.com.br, but it is not possible, without comments to a message "The username which you have entered belongs to a different deployment/region" that I receive. I have already registered no domain zohomail www.fortalezaferroeaco.com, if that is why, what should I do?
