I am sorry to hear that you are having this issue.
Go to the Amazon icon in Roku, and select it like you were going to watch something.
Then it will give you a website and activation code.
Then leave the Roku box alone, and go to that website on your iPad or computer, and enter the activation code.
It may ask you for payment information if you haven't done so. Once you set up the account online, it will automatically communicate with Roku, and you will be ready to watch movies.
Wait for Roku to completely finish before touching any buttons.
