Windows 10 Home, Finale 2012

I'm just trying to merge a string quintet score and parts together, to make them into a pdf of the SCORE AND ALSO EACH PART that I can send to the group.

Scoremerger isn't, uh... merging.  It's chopping the pages wrong, whether or not I "insert page breaks" etc  (have tried just about every possibility), and, even when it gets all the parts right, it doesn't append the score.

I will probably just make them each a pdf individually, and send them in a zip file, but was curious if the software could merge them into a single pdf.

Ideas?

Thanks!
