Camtrace in Q3 (for cpma)

Hi, I need some help in making a camtrace for promode in quake3, never done it before and I'm bored so I thought I'd make one, when I try to load the De-frag mod in the mod selection in Camtrace3D it just crashes though so I don't really know how to get around this problem :S Would be great if someone could help me out!
