Clip Art Gallery

Version: 2008
Operating System: Mac OS X 10.5 (Leopard)
Processor: intel

I recently Office 2008 for Mac. It has been a little buggy, but overall,
it has worked great. I noticed one day when I went to open the Clip Art
Gallery in Word, Excel and PowerPoint that there was a problem. I get the
following error message from the Office program:
----------------------------------------------------------
Word/Excel/PowerPoint cannot launch Microsoft Clip Gallery. Microsoft Clip
Gallery may not have been installed properly on your computer, or may not
have enough memory available to launch Microsoft Clip Galley.
----------------------------------------------------------
Then I also get a system error:

The application Microsoft Clip Gallery quit unexpectedly.
----------
I get 3 options then after that: Ignore, Re****t or Relaunch. When I
relaunch it, I still get the same messages.
I HAVE reinstalled Office hoping that would correct the problem but I
didn't.
Can anyone help?
