Re-doing the VA (Descent Vehicle) mesh.
I noticed something interesting about ShipEdit, Blake's Blender Tools and Blender : ShipEdit crashes when you load some meshes. It kept happening, but it seemed that cleaning the meshes, removing "useless" objects in the Blender scene did the trick. Now I found the issue : in a Blender scene you can have "empty" objects, objects that have no vertices because you removed them all. Blake Tools translate this into an "empty" meshgroup, and Shipedit can't deal with that. So be sure to clean your Blender scene before exporting.
