Hi there,
via the link on this page

I downloaded these instructions:
Unfortunately, the file size is so large that the work with it is impossible. I wanted to cut the PDF with Acrobat print-friendly on A4. Acrobat is so slow that I gave up.
Please generate the PDF again with useful parameters. As big as necessary, as small as possible.
Just like here, this size is good:
mAuriga_The Mars adventure of Mark-Chapter 2: Argot.pdf
Many Thanks
Gerhard
