In Presenter, if you see a message about an invalid or expired token, it means that you need to reconnect your SongSelect®.
In order for WorshipTools to access SongSelect, the church needs to sign in to CCLI from within WorshipTools using a valid CCLI Profile login. These logins often belong to a specific individual that serves at the church. When that individual leaves their position, they may be removed from the CCLI user list. This is what causes the link from WorshipTools to CCLI to sever (or the token to become invalidated).
To fix this issue, you'll first need to be an Administrator on the WorshipTools account. If you are not an Admin, please contact your Admin for help.
Click on the ⚙ gear icon in the top right corner of Presenter and select Settings. On the following page, open Connections from the left-hand menu. Disconnect SongSelect, then reconnect with an active SongSelect login for your church. Doing so will re-establish the connection between the two programs so that you can return to importing songs from SongSelect without issue. You can also fix this error in the Music Stand app.
For any SongSelect support, please contact CCLI directly.
