I installed the demo on my Comp/con and while it is listed as something I have, the page with the list of the downloadable content says I don't have it and I have none of the materials in the book availabe.
Same issue, bought the bundle. Everything except this free one loads.
The content pack shows it's loaded, just missing the checkmark on the directory side. Will have to test later to see if the content is actually missing or if it's just a visual bug.
