Pally,
I just ran your model on a LINUX box. Here is some extra info and
additional steps that were required:

Both images (image5_axel.hdr and axel.hdr) don't show the ghost
luminaires that you have in image5.pic. No idea what's going on.
I also inspected your model in Rhino3d. The surfaces that IESVE
generated can be a bit weird, especially when you don't enable 'inner
volumes'. In your case, the walls at least are good, with no co-planar
surfaces.
Cheers
Axel
