Every day I try to open a file I was working on the day before and it shuts down. I can see a preview of the file, but it won't open. The backup file won't open either. I was having this problem on build 1493. I upgraded to 1812. Same problem. This is killing an entire day of work every day. The only work I retain is the G-code from the tool paths I had generated. The actual toolpaths are gone with the drawing, of course.

I love it when I open a drawing for reference and it shuts Bobcad down before I remembered to save my work from today.
