Hi there, I am Cris and will be glad to assist you.
Can you tell me what browser you use? Is it Internet Explorer, Chrome or Firefox?
OK, when you open a second tab for Pandora.
Does Pandora not play?
OK, I am not offering remote services and you do not have to sign up for subscription.
But you have not answered my question to further assist you. Have you tried to open Pandora on a second tab?
