I have downloaded both zips. In zip 1 you will find all of the Geometries, Libraries folders have those items. In zip 2 those folders are empty and just has the textures. Generally we ask that the empty folders be removed...but this product has been out there for a while and maybe it wasn't done then. I have corrected the zips and reuploaded them. I have also reset your downloads so that you can download them again. 

Have a good day!
