My colleague with a similar installation as mine cannot open or reference dwg files in SS2.  The error message is "The *.dwg is not in a recognized file format.".  However, I can open and reference the file, and it can be opened in earlier versions of Microstation.  What should we look for to solve this?

What program was used to create the drawing?What program is being used to try and open the drawing?Isn't the SS2 an Indonesian assault rifle?  Or is it an experimental aircraft?  I forget.
