Interesting document :-), I'm going to read it through, certainly the 'extending' part.
It's strange though, running ubuntu here I installed adobe reader as you suggested, but I only get a black page, nothing more.
Using okular I get a message with an add to adobe reader, and a message that says there are several files embedded. I get the option to extract them as seperate files, which I did. Then I could read everything perfectly well.
It is weird that here it works better without adobe reader. Adobe Reader here is reader 9, probably yours is newer which would explain a different experience.
Grtz,
