.documentElement or .XMLDocument is null or not an object

Problem:

The following errors sometimes appear in Libronix after an update to version 2.0

• Line 65 (HomePageLBS.html): 'Util.LoadXMLDataIsland(...).documentElement' is null or not an object
• Line 287 (PassageGuide.html): 'SingleResourceResults.XMLDocument' is null or not an object
• Line 300 (SearchResultsStandard.html): 'SingleResourceResults.XMLDocument' is null or not an object

Other errors that include these details:

".documentElement' is null or not an object"

or

".XMLDocument' is null or not an object"

Solution:

Reinstall MSXML3 SP7 to fix this problem. Click on the link below to initiate the installation from the Microsoft website:

MSXML 3.0 Parser Service Pack 7 

Reboot your computer and the errors should cease.
