If you publish your presentation to Word in Presenter '09, you may find that it does not work properly if the entire file path for your publish location is greater than 100 characters in length.
This is a known issue. You can work around it by publishing to a location with a file path of 100 characters or less.
Note: The entire file path starts with the drive letter (C:) and includes all slashes and spaces. For example: C:\Users\User Name\My Documents\My Articulate Projects\Presentation Name
