In your Raze folder create a subfolder and copy the following files there
BLOOD.INI
BLOOD.RFF
SOUNDS.RFF
TILES000.ART to TILES017.ART
SURFACE.DAT
VOXEL.DAT
You will have to buy a copy. I'm locking this because I am not going to let this thread devolve into a discussion of "how to get an illegal copy". You can get a legit copy through the link above - best to leave it at that.
