I have been using Draftsight 2020 for over 6 month, it was working fine up until now. Every time I open CAD drawing from other it work perfectly fine, but today I try to open and print a CAD drawing sent into me by other Draftsight crashed. When I try to open draftsight again it would no open normally, all that appears is the Draftsight Crash report dialogue box. No matter what I do the same thing happens. I have try restarting computer the same thing still happens. Any one have any Idea how to fix this?
