mdx file preview not support.

If it doesn't load Textures files you need:
http://download.kingpin.info/index.php?dir=kingpin/main/textures/Lighting_wal_files/&file=lighting_wal_files.zip
It's possible to put Map type on QUake III and it then loads tga textures, just not sure if every brushes then work.

If Jack does not start under linux you can use the command: ldd Jack
to see what shared libraries are required and install them.
