Email swap

Hi, I need assistance replacing my current email. My email grady.bain@yahoo.com is no longer active and has been shutdown by my email provider yahoo. I tried re-opening/creating the same email again but yahoo doesn't allow me to and I have contact them and they said there's nothing they could do on their end but recommend I try and make a new email. I would like you guys to update my email to bain.grady@gmail.com. Hope to hear from you guys soon as it is important for me not to lose my account.
