Listen could somebody please have the decency to help the rest of us who can't run the game? I've tried reinstalling the game, checking the cache, deleting the bin and then recovering the missing files, and updating all drivers on my pc but to no avail. All the game does is start the launching program window and then does nothing. Every time I verify the cache it still says a file is missing. So far it's looking like it was a waste to buy Portal 2 on Steam.
