Steam Authentication: Failed
I saw this on top left of the main menu of DEFCON and I am pretty curious about if that means anything. I just began to play the game and only having fun (by nuking millions of people) by playing with AI, but will it mean anything when I make my mind to play with people?

Try deleting the authkey file in the installation folder. If that doesn't fix it your firewall might be blocking the game from the authentication server.

Deleting the authkey resulted in game considering itself a demo, it didn't happen before. My firewall is disabled, so it is very strange.

Got the same problem. Says key is invalid and forces the demo version of the game.

Uninstalling and installing again worked for me.
