Hi when I try and save a project or even just a blank project I can as it comes up with a message "The program Must close before the program closes you can try to save changes in c:\\Program Files\\Drafsight systenes\\Draftsight\\bin\\NoNAME_0_Recover_2017-04-04.dwg any changes that are saved are those prior to the last command you used do you want to save changes" when I click yes it just crashes all to gather I can navigate to that path but no save file is  there and the only thing I did at lunch is just click save 

I have installed the critical fix things but same issue Need help OS is windows 10
