Required module "propresenter"

[Appl3Tree]

I've run through the steps to install npm, modified my config.js then ran node app.js.
After running it, I receive the following:

internal/modules/cjs/loader.js:905
  throw err;
  ^

Error: Cannot find module 'propresenter'

Poking around further, I did see that there is the node_modules/@utopian/propresenter directory though updating config.js to require ( "node_modules/@utopian/propresenter" ) did not make a difference.

This seems like a fantastic creation to make up for ProPresenter 7's lack of a master module which would be the sole reason my church would be able to upgrade. Otherwise we're stuck waiting on RV to come out with something to replace it.
