importing/exporting errors dealing with normals/uv

Hi i have a problem when i import a model as a .obj in milkshape and export it as a .xsi for soft image xsi. When i import the .xsi into softimage, quite a few normals don’t match the texture that’s supposed to be there. If you go to the website below, you can see pictures of what i am talking about. Can anyone help me fix this problem? Is there an easy solution rather than me doing the whole uv thing (which i don’t know how). ANy help would be greatly appreciated!

p.s. if this isn’t the correct place to place such issues, please let me know where exactly i can post this problem.
