Hi    ?I get this error when the program start

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

in:/Volumes/DraftSight/NONAME_0_recover_2010-12-06.dwg

Any changes that are saved are those prior to the last command you used.

 Do you want to try to save changes?

I try answering  yes and no ,it has not fix the problem I also try reinstall program ,with no luck I hope that someone has a anwser for me

Thanks
