Portal 2 Starts but then shuts down...
Everytime I try to start Portal2, it says 'Launching game...'. My friends get the message pop-up that I have started playing Portal 2. Then, after about 5-10 seconds I go back to being blue and out of game. Nothing else pops up, the game just simply won't start.

The kicker is that I was playing the game only a few weeks ago... What gives? And more importantly, why does no other game seem to have this problem??

What he means, is if you right-click the game in your library, go to properties, and click on the "local" tab, you have an option to verify the integrity of the game.

Apparently this has helped some people who have this problem. But I have the same issue you described exactly, and it hasn't helped me at all.

I have the solution! The game shut downs because portal 2 is missing one file. First shut down your antivirus program because portal 2 don't likes it, and then re-instal the game. And play the game with offline antivirus program because the antivirus will delete one of your game files. That helped me, and sorry for my bad english :)
