word x unexpectedly quit

[001011010001101011]

I'm using OS 10.4.1 and Word X. When I click on "OK" or "Cancel" the
application quits. It also quits when I click "Open" after I chose the
file. Occasionally I'll receive a message (following the "unexpectedly
quit" message) that reads:
"Database Daemon-New Settings
New settings have been created for this application. Do you wish to
use these settings from now on?"
I attempted to download a new font today, but it didn't download. I've
searched my HD using the font name, but found nothing. I opened font
book and "Resolved Duplicates", but that didn't help. I've also tried
placing the "Normal" template in the trash, but that didn't help
either.
I am able to open Word by holding down the shift key and choosing
"Open" from the File menu.
Thanks in advance for your help,
Brent

Thanks, Daiya. While reading the Add-In section of the link you gave
me I remembered I recently installed Acrobat Pro 7.0, which contains
PDF Maker, which was the culprit. I got rid of it and Word functions
normally again.
Thanks for your help,
