Can not login to Zoho mail: Account is disabled

Hi,
I've registed at Zoho. My Zoho account is hieuvotrung91@live.com and I've actived my account via email. I can login to Zoho home too.
But when I login to mail.zoho.com, I got the message " Account is disabled ".
Could you active my Zoho mail account, please!
I also attach a snapshot with this ticket, thank.
