I had DraftSight installed on my computer a year ago.  In the last couple months I had to have my hard drive replaced.  After that I reinstalled DraftSight.  Now, for some reason I cannot open any of the files I created in DraftSight 6-9 months ago?  They are just the regular .DWG files that I created in DraftSight.  Can anyone help me?  I would hate to have to recreate these!!
