I do not import my materials or objects.  What I do is create a folder under materials, let's say I name it UVDan materials.  Then I copy my materials from the older program versions to that folder.  This has worked for me from version six onwards.  I do the same for Obp files that I created in earlier programs.  With Obp's I have folders for aviation, special effects, animals, people, buildings, and ships.
