I believe they disabled the link when Right Hemisphere took it over. I can't remember what the original program was called ... wasn't it something like 3D Exploration, or something to that effect? At any rate, the free version was taken down from its original site when it was bought out. I purchased RH's version and have since upgraded to the most recent. It does a real good job at translating file formats. I second the vote on converting to OBJ.
