I have had something like that when an .obj couldn't be found. Check the CR2 for the location, see if it is there. I have also heard that the .RSR in the geometry folder can get all B'JIGITY. I haven't done it, but I have seen recommendations to delete the .RSR, it is supposed to be replaced the next time the .obj is opened by Poser. I am not sure, due to the fact that I have never needed to do anything like that. A second opinion is probably best.
