QueryInterface for interface Word._Applicati on failed.

Hi, does anyone have any experience with this error?

I had a asp.net app that opened a word doc stored on the server, filled in
some information, then mailed the word doc to the user. This was all working
fine except for the fact that i had noticed WINWORD.EXEs were being left
behind on the server. On someones advice i updated to the latest Office 2000
SP, and have had this error ever
since. I have since tried: repairing office install,complet ely
reinstalling office,complete ly reinstalling visual studio to rebuild app,
reinstalling framework.. none of these have had any effect. It seems the SP
may have impacted the word object library (its the 9.0 library). The code is
as simple as:

Dim oWordApp As New Word.Applicatio nClass
Dim oWordDoc As Word.Document = oWordApp.Docume nts.Open(fileNa me, missing,
false, missing, missing, missing, missing, missing, missing, missing,
missing, true)

As i mentioned it was working before the Office SP but now bombs on the
second line, even tho i'm back to the original office install. (I even tried
running Office Eraser to get completely rid of office before putting it
back).
P.S. the ASPNET account has rights to launch word under dcomcnfg

This one is really driving my nuts.. anyone got any ideas??
TIA
Lee.
