The latest No-CD Sacred patch is incomplete, I suppose out of concerns about distributing CD keys. But Sacred does not have CD keys you say. Indeed it doesn't, but the Russian Plus version and updates are Starforce 3 protected so the CD itself contains a single Key for the CD like all Starforce 3 CDs. My Sacred CD like all non-Russian versions uses Protect CD rather than Starforce 3
There is more info in other game forums that will resolve all of your questions
I'd rather not show a direct link
