Error in Visio 2002 update

[Art]

I just did an "Office Update"for Office 2000 and Visio
2000.

The updates had 2 parts:
Part one did a SP(3?) update on Office 2K and Visio 2002.
This went well - I was asked for the original CDs for
both programs and they updated successfully.

Part 2 - the other stuff for Office 2K and Visio 2002
went OK for the Office 2K part (I was asked for the Office
2K CD), and was unsuccessful for Visio 2002 (It did not
ask me for the visio 2002 CD).

After that, when I try to redo the update, I do NOT get
another download, just the install - which does NOT ask me
for the Viso 2002 CD - and is always unsuccessful.

Now when I open Visio, I have to wait several minutes with
a message box that says "Please wait while visio updates
its directory cache".

Anyone have any suggestions?

Thanks,
