Duke 3d 0.4c

Well, I upgraded to this thinking not much would change, according to the read me their was a slight speed increase and not much more. I copied it over my old files, ran it... crashes back to the today screen every time. Anyone else worked on this? I am going to do a line by line examination of the cfg. With this version the midi support doesn't work either. just makes a lot of LOUD screeches.
