In my experience its faster to save to an external drive or ram stick than it is to save to disks. I have nero and a dvdrw and it often takes forever to do a decent backup.

One thing I keep my eyes on is whether the zipped directories are set up correctly. Some stuff unzips to a god aweful mess.

I downloaded a couple of the files to have a look, and the *pz2 [pose] file is just slapped in the textures folder here:
RuntimeTexturesLyrraMildragLM_mildrag_amberLM_Mildrag_Amber.pz2
That file needs to be moved to an appropriate directory in the RuntimeLibrariesPose directory. He likely has All the pose files in the wrong place.

Oops, I just downloaded the MATs [http://www.cyclopsstudio.com/zips/LM2003Mildrag_MATS.zip] file, and the pose files are in the RuntimeLibrariesPosesLM_Mildrag directory.
