iTunes won't accept Existing Apple ID
I am a new Macbook user and recently bought the new Macbook Air 13' (2015 update). The problem I am facing is that I can't login the iTunes store using an operational Apple ID. I have confirmed the details of the ID and password, and am using the same details for FaceTime. However, whenever I use the same login details in iTunes, the following message is displayed:
"This Apple ID has not been used with the iTunes Store.
Please review your account information"
That's it...
Please advice on how to go about this.
