Error when exporting 1200 x 1800 image

I am making a poster (24"x36")for my programming class, all done with just NodeBox - including printing out the code on the poster. Based on sample image
size(1200,3600)

I can Python|Run to generate the image,
but upon export to PDF, JPG, PNG - anything I try,
Nodebox shuts down. Error log below.

Code also below that

Any help would be appreciated
