Hi Shaun. I finally had a chance to look at the files.
The first thing I see is you're not using the instruments that are defined from the S7S Template. From the Readme, please review page 9 for adding instruments to the score, and page 24 on how to Export Manuscript Paper (alternative to making copies of Template .sib file). A thorough read of the entire document may be warranted at this time also.
The screen shot of your Playback Configuration was too small to make out what is there. If you're using the "S7S SoundSet 7.1a" sound set, you'll be good once you start using the instruments from the S7S Template definitions.
One other thing you can do is playback the PlayTest files to get an idea of what the S7S Template and S7S library are capable of.
Let me know if you have any other questions.
Hugh
