Howdy, I'm making some courtesy bug reports.
I didn't do a full scan on your haks, but I am scanning a lot of portrait collections for errors right now, and I found these:

._GiliorPanther_H.tga is not a valid resref
._GiliorPanther_L.tga is not a valid resref
._GiliorPanther_M.tga is not a valid resref
._GiliorPanther_S.tga is not a valid resref
._GiliorPanther_T.tga is not a valid resref
po_hu_f_IrishGirl_H.tga is not a valid resref
po_hu_f_IrishGirl_L.tga is not a valid resref
po_hu_f_IrishGirl_M.tga is not a valid resref
po_hu_f_IrishGirl_S.tga is not a valid resref
po_hu_f_IrishGirl_T.tga is not a valid resref
TobiasSandybanks_H.tga is not a valid resref
TobiasSandybanks_L.tga is not a valid resref
TobiasSandybanks_M.tga is not a valid resref
TobiasSandybanks_S.tga is not a valid resref
TobiasSandybanks_T.tga is not a valid resref

This is disregarding the jpg/gif source textures, and the txt readmefiles that are also included.

The longer file names need to be shortened, while the ._GiliorPanther files seem to be hidden "temporary" files that must have ghosted over from working on them from the directory at the time of export.

Cheers!
