Finally! Someone having a similar problem to mine!
I had a corrupt user profile and had to create a new one. I've managed to
port all of my messages and contacts over, but when I set up BCM, it didn't
see my old database, my only option was to create a new one.
I can see a .ldf & .mdf file with my previous database name, but I can't
"see" it.
Any ideas?
