Thank you for your information.The owner and operator of register.to has died. So no one currently manages the site. The national registry Tonic.to has terminated cooperation with Register.to. Contact Tonic.to directly and they will help you.
I went to Tonic.to and had them reset all my handles/passwords as they had control over all the names under Register.to. I transferred them slowly over to Namecheap as their prices are great for these.
