Thanks, Raze. You're on the ball tonight. I think I'm long past the dialogue with Louis, but now I have another problem. I did go down the fourth tunnel in the crypt after defeating Amdusias. When I got to the end, Damian showed up and gave me some guff and then disappeared. When I walked up onto the transporter, nothing happened. It won't dialogue with me, even with a right mouse key.
Also, power went down while I was playing tonight, and now the sound is gone, even after a reboot and a restart on the game. If I reload from disk, will I lose my game progress?
Thanks for letting me pick your brain!

There IS only One/Three!
