Surface file corruption

I am having a problem with surface files continually getting corrupted.  I am creating a new surface by importing breaklines into the surface (file -->import --> surface).  I am importing these features as single elements.  When I go to display them on a profile, they generally display the first time.  If I close the file and re-open it, and try to display the surface cross feature on a profile, inroads freezes or shuts down immediately and the file is then corrupted.  I am at a loss as to why these files are continually getting corrupted.  They are not large files.  Is there something about importing a feature as a breakline or contour?  Or is it something with the styles?  Or could it be something with the way the particular inroads and microstation versions I have interact with each other?

 

Microstation version 8xm revision 8.09.04.88
