check if the user profile of the affected account (Profile.xml) is corrupted? You can check by opening the Profile.xml file with Internet Explorer, and see if any error is returned.

Note:
User profile of a backup account is located in its User Home db folder –
${UserHome}\${Username}\db\

If the affected profile is corrupted, recover a previous version of the user profile by renaming ‘Profile.xml.1’, ‘Profile.xml.2’, ‘Profile.xml.3’, or other subsequence xml file to ‘Profile.xml’.
