It's probably easiest if you can update your 4.61 version to 4.67 which is probably easier. You can either use the Check for Latest Version option on the help menu or you can download and reinstall the full version of Help Builder which installs right ontop of the existing version.
You can also use the newer files in the older version but it's probably better to update to make sure you're dealing with the same structures.
