Game will not start. Opens the "Preparing to Launch Syberia..." window over and over.

Just loops open/close/open/close on the "Preparing to Launch Syberia" Steam notice that you see when you start any game. After a second, it closes, then immediately re-opens, and goes on and on until I finally am fast enough to click "Cancel"

try to launch the game with the application on the folder SteamApps, Not directly with steam.

Try opting in to the steam beta then switching back or vice versa. Sounds like an issue with steam not the game itself.
