Hi and Welcome. My Name is ***** ***** I look forward to assisting you today with your question.
Instead of creating the account from the Kindle itself, create it from your computer.
On your computer, go to this site and create your account from here --> http://amzn.to/1u4BsVR
Then use that account to sign in to your Kindle. If you have any difficulty creating it yourself, please let me know by replying in here and I will create the account for you from here.
