Hello! There is a folder off the root called 'ACCOMPANYING MATERIALS' -- but it's only included in the full version ($6.99 or above). Hope that helps!
Viewing post in Where is the bonus material located?
It's the only other folder inside the zipped folder you will have downloaded. If it's not there, I'm confident you don't have the 'FULL' version.
If you contact jamin[at]superstring[dot]studio I can check your email address and see which files you got. I can also send you the accompanying materials manually :)
Thanks!
