Same for me. I had downloaded the dll for Expansion2 after I got the email. Then downloaded the demo - that was 3 GB and created a new folder in SteamApps/common. The demo runs alright, and I can still run G&K from both the normal icon and from Steam client. But no sight of BNW and no obvious way to force it, even after verifying the cache.
that was murder. Decided to reload the PC, but our friends at M/Soft decided to install 20 patches. After an hour it seems to have got stuck on the 19th, so I forced a power down and back up. Put the installs in again, quickly, and closed down again. Then rebooted, started Steam and we started on the download. Another 45 minutes and I should have the game.
