MSBusinessContactManager update fails and stuffs BCM

I am running Outlook 2003 with busines contact manager. Have been for years.
The update manager said there was an update for the business contact manager
for Outlook and I ran it. It hung totally on installing something like SQL
server small business edition. I had to kill the install. I rebooted the
computer and re-did the install (it seemed ok) and ran outlook and was
requested to either start new BCM database or use an exisiting one. Both
options failed to work on multiple attempts. I assume SQL server SBE or
similar didn't install properly, but checking for updates said my system was
up to date.

I then uninstalled the BCM for outlook update which seemed to uninstall BCM
as well. I then re-installed BCM for the original Office CD. Outlook now
crashes on every boot. the BCM for office update says I don't have a valid
version. So now I don't have BCM at all. But I do have backups of my BCM
database (MSBusinessContactManager.ldf and MSBusinessContactManager.mdf)

Please help!
