DraftSight has stopped working

Hello,

I don' understand, I can work on DWG file, but with some files, DrafSight can't open them and crash immediatly.

 

I have unistall draftsight ( 3 times ), and each time, I've delete all files of draftsight found on my pc, and make reboot before to install again drafsight.

You can see the error in the attachement.

 

I have a PC with WIndows 8  64 bits

 

Thanks in advance.
