I have read several posts with the same or similar problem, but I was not
sure if it was exactly the same.

I have un-installed MS Office Small Business and re-installed. Then I
followed the directions and installed all available downloads from the web.

I am running XP Professional, SP2.

I can not find the KB908531 to un-install, as was mentioned in several of
the posts I read, or I would have tried that. I also was unsure about
clicking on the link in one of the posts that referred to MS06-015, because
it mentioned that it could cause other problems. Please help.
