"vn" lines in the obj are vertex normals. Your vn's seem to be corrupt (IND could be "indefinable"). What program wrote the obj? Poser doesn't use the vn's, but it needs to know the proper vn data, to rewrite the "f" lines. The corrupt vn's could cause problems. You could rewrite the vn lines with text editor, like vn 1 1 1 and save a new obj. Then, import the new obj in UVMapper, and export without normals, to make the obj more Poser-friendly.
