If you open Outlook and see the BCM Menu, and can select Create or Select
Database, you will get the Screen that allows you to choose or create a DB.
You can select one already created IF it exists on the machine, and in the
location the BCM install is expecting.
Data in BCM 2003 is stored in the MSDE as *.ldf and *.mdf files .The default
location is C:\Doc & Settings\<user profile>\Local Settings\Application
data\Microsoft\BCM
So you can find where you parked the DBs you created before and put them in
the right place. You did make copies, backups or burn them to CD, right?
