Trying to decode 3w files into gcode.

I have a friend who needs some 3W files translated into gcode. It's for a DaVinci, one file is sliced in Simplify 3D 4.1, the other is sliced in Simplify 5.1. Yes I know Simplify gives you both gcode and 3w format, but 5.1 isn't working for the Davinci and we don't know why. I've tried the python port of Threedubber, miniMover, dV3wConverter, and DecryptXYZ3W but nothing works. I just get a 0kb gcode file as a output. Is there any other way to decompile a 3w file to get the gcode inside?
