I have the same problem. I have purchased a Intel i7 7700K which was offered with 2 free games - Assassin's Creed Origins and WarHammer II, once I use the key as instructed via the designated URL it comes with the message - "Expired Master Key". Can you help please?
I would recommend that for issues related to starterpacks you reach out their support directly, as far as I a aware Intel doesnt provide support to it through this forum, here is the URL:
I tried your link and it redirects me to this page : https://communities.intel.com/news (which i suspect is the homepage for this forum).
I've got the same problem (the expiration error), i would very much appreciate it if somebody can help me or I can be redirected to a link that can help me in this matter.
