I bought Divinity Original Sin EE Standard a while ago. Today I bought the Collectors Edition for the extra goodies. After purchase I don't have it available:
1) HD wallpapers
2) 'The Prophecy' prequel story (31 pages)
3) The Lady, The Mage, and The Knight tech demo
4) 'Child of the Chaos' novella
5) official strategy guide
6) Manual 37 pg
Soundtrack, Design documents and Artbook are available.
Can you advise me where the problem is?
This goodies are available after install game only?
Thanx for reply.

Weird, I only see these too:

manual 10 MB
wallpapers (3) 7 MB
avatars (20) 3 MB
artworks (43)10 MB
design documents (53) 203 MB
soundtrack (MP3) 99 MB
soundtrack (FLAC) 688 MB
artbook 44 MB

Btw I asked support, but they haven't replied so far..

Me too.

Guys, support finally replied.
They said that such extras can be found in the Divine Divinity and Beyond Divinity entries.
I can confirn they're there, so.. case closed.
