So the secret questions appears to you and you don't know the answer?
Sorry, never happened to me.
No, there's no secret question option because I never made them.
I made a Steam account to play the Orange Box. Back then it was a quick sign up process
Then I had to download the Steam Client
Put the disk in
Install the game
Put in the CD key thing (There were like, 3 of them because the Orange Box was 3 games)
Then I had to find the games in my steam library (Remember it being really difficult at the time)
Launch the game
Game crashes and demands update
Update the game 6kbps/648MB EST TIME: 2 days 8 hours
Go away, do something else for half a week.
Come back, open the game.
START PLAYING THROUGH THE WHOLE ORANGEBOX.
