I am getting this message when I try to view the features within my existing dtm.  I am not sure if this is a sign that it is corrupt or what. I essentially cannot see any of the features in the Feature Properties dialog box or the Update 3-D/Plan Surface Display dialog box.  I can still run my corridor modeler and see the existing dtm.  The problem is fixed when I get out of Microstation and Inroads and get back in.  But after a couple of corridor model runs the problem comes back in that I cannot see any of the features in the existing dtm.  This only occurs with the existing dtm.  Any suggestions?
