    dwg files unknown format

    GArshamA Level 1

      I have a colleague that has sent me (multiple times) a dwg file done in AutoCad that I can't open.  It keeps saying "the file ....dwg is an unknown format that can not be opened".  I have CS5 and I thought Illustrator easily handled dwg files.  Any clues as to what the problem could be?
