The Token expired error means the session has been there for longer than three days and usually comes from "recycling" an event — adjusting the start/end time of an event after it has ended to be live again. 

To get rid of this error, you can remove the session and create a new one. Or you can go to your Key Details page, deselect Sessions, hit Save, go back to Key Details, reselect Sessions, and hit Save. This will create a new Sessions token and remove the expiration error.
