One of the reasons you might see a "token invalid" notice is because the person who initially connected CCLI's SongSelect to Presenter has been removed from your ministry's SongSelect users list.
To fix this issue, 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 a current SongSelect log-in 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.
For any SongSelect support, please contact CCLI directly.
