I am Vinod. I will try my best to help you resolve this issue.
Let's check whether the itunes is updated to the newest version. To check the version,1. If you have a mac computer, open itunes. You will see an apple logo to the top left corner of the computer followed by itunes, file, edit, view etc. Click on itunes > about itunes. That will give you the version.2. If you are using a windows computer instead, open itunes. On the top menu, where it shows File, Edit, View, Controls etc, click on Help > about itunes.Let me know which version of itunes you have.
