I recently upgraded to OneNote 2007 from ON2003. When I try to edit sections that were brought over from the 2003 sections I get an error message that reports I am using a section created in an earlier version of OneNote that needs to be upgraded. When I click on the message it begins the upgrade but I then receive an error message that indicates that OneNote has encountered a problem and cannot complete this operation. I have all the upgrades installed in Windows XP. I reviewed earlier questions in this forum from 2006-2008 but did not see that the problem was ever fully answered. -- Thankyou, Scott.
