Thanks for your response but I've since discovered why Poser was crashing. By mistake I was using an older version of Maconverter. After I discovered it I downloaded the newest version. The new version deals with the problem of corrupted previews and that was, apparently, exactly why Poser was crashing. Thanks, again!
