Draftsight closes when duplicating layout tabs

I've been using the program without issue for about 3 months. Recently I simply right-clicked on a layout tab I wanted to 'Move/Copy', and it gave me an error message and closed the program. It allowed me to save work up to that point, and I can re-open the program, though each time I try to copy the tab, it does the same thing. Even after repairing and uninstalling/reinstalling the program. Also, it will not let me print...comes up with an error message in the command line there too.

Any ideas of a fix? Thanks
