This problem occurs if the Building Blocks.dotx template is damaged or corrupted.

There are two copies of the Building Blocks.dotx template. One copy is stored in your user data folders. The other copy is stored in the Document Parts folder in the Office 12 folder.

Typically, the copy that is stored in your user data folders is the copy that is damaged. However, both copies could be damaged.

The following Ribbon galleries are affected by this problem:

•	Autotext
•	Bibliographies
•	Cover Pages
•	Equations
•	Footers
•	Headers
•	Page Numbers
•	Quick Parts
•	Table of Contents
•	Tables
•	Text Boxes
•	Watermarks

To resolve this problem, move the damaged copy of the Building Blocks.dotx template out of the user data folder. After you do this, Word 2007 creates a new Building Blocks.dotx template by using the default content.
