I did, first, I tried the registration key, nothing came up, so, just to be safe, I tried the download password, nothing showed up, then, I continued my game and I could go past the execution in the story. But, at the top of the screen it does say it's a public demo, are you meant to download it into your hardrive, or does the demo change. And, when I right click, an option at the top says 'get the full game.' Does something come up, and, even if I didn't download the non-demo, how come I can't go into Somnus?
