OK how about trying to repair the installation...
Click start> control panel> then select add/remove programs.
scroll down till you find Microsoft Office 2007 click on it, then click the button that says change. when the window opens up you'll have three check box choices select Repair and click next...

Also Microsoft Office word 2007 does have a feature under word options> trust center> trust center settings button> privacy options.. you'll see a choice of "downloading a file periodically that helps determine system problems". you can check that and see if it helps, I didn't think you would be interested in using that feature but just in case the install repair doesn't work (I did use this feature in the past and it did fix my problem then I just went back in and disabled this feature, only thing is the problem I had was not like your problem...well hope this helps..
post back with an update if you could...
