Drawing appears empty when opening in DraftSight

Hi,

I am having a problem with your DraftSight program.

Yesterday I installed windows 7 on my computer and download the draft sight program and when I go to open one of my drawings in DWG FORMAT it opens up without the drawing shown (no geometry displayed).

I did not have this problem when I had windows XP.

Could you please advise me what to do.
