Hello, I've been using DraftSight 2019 for several days and I have serious problem. When I opening project (but not every project), my DraftSight is jaming. I can't do anthing. When I'm trying to shut down program by crtl+alt+del. my whole system is crushing. I can't eveen reeboot system. I haven't such a problem when I was using free DraftSight 2018. I was starting program as an Administrator and without Internet and with anty-virus turn off. Reinstalation and repair not help too. Plese help! I'm sorry for my English
