How to Fix Insert Page Number Issue in Word 2010

Office Word 2010 references a file called Building Blocks.dotx to create the page number.

On Windows XP installation the file is located at,

C:\Documents and Settings\username\Application Data\Microsoft\Document Building Blocks\1033

On Windows 7 or Vista installation the files is located at,

C:\Users\username\AppData\Roaming\Microsoft\Document Building Blocks\1033

You will need a working Building Blocks.dotx file from another computer with Word 2010 installed and copy it to replace the file on the computer that's having the issue.
