For the long script running, that might mean you have had Pandora open for too long. Sometimes when i keep my pandora on for ,like, 3 days, and it gave me the long script running notification. To fix it, restart the app, or refresh your device. Works for me. As for the account thing, that may mean someone else is using your account on a separate device, or you have a pandora window/app open on another device.
