Cannot open SU Pro file or login to Trimble

I have not been able to open a SU Pro file to work on, or start a new file for the last 24 hours. I last used SU three days ago. When I attempt to use SU, a tag pops up that says, “Authorized Token cannot be used…sign in…” When I go to SketchUp/Manage Licesing, it asks me to sign it, but when I do, it grays out. I can go to Trimble and confirm that I am an active Pro user until December. What is an Authorized Token? Have I missed something in the last few days?
