OneNote 2010 just started syncing to the wrong skydrive account.  My previous notebooks would no longer sync so I closed and tried to re-open.  It turns out it could not because it was now linked to a different account (a new one recently setup for a different business).  It now, will only link to notebooks under that account.

I've tried unlinking sydrive from the system tray, and relinking.  SkyDrive itself shows the correct account, but OneNote still does not.

I've tried opening the Notebooks from IE into OneNote, nope.

I've clicked (Not XXXX?) on the Open Notebook page and it does nothing but refresh with the same, wrong, account.

How do I detach OneNote from the wrong account?
