Problem opening DraftSight on Win7 32bit

I'm running Windows 7 Professional 32 bit, and when I try to open Draftsight, often it crashes immediately.

A couple of popup windows come up, but the only one I can see says:

This program must close. Before the program closes, you can try to save changes.

E:\\Program Files\\Dassault Systemes\\Draftsight\\bin\\NONAME_0_recover.2015-11-21.dwg

Then the program closes itself.  

I've tried uninstalling, stopping the antivirus an reinstalling (everything as administrator), but I experience the same problem.

When sometimes it starts, I can draw what I want, and also I can save it.

But if I try to open my project, DraftSight crash immediatly.

Can you help me to solve this problem.

 

Thank you.
