Movie Clips Not Playing After a Few Seconds

[SChaput]

I have been trying to create a game similar to helicopter in which you control an object using spacebar and avoid obstacles and a timer keeps track of your score. My Problem is that if a certain amount of time passes on the loading screen and you initiate the game, the obstacles do not start to move across the screen. If you start the game within a few seconds of loading, it works fine, other then that, no dice. This is currently my largest problem but another severe issue is the timer that seems to start at the begining of the flash movie no matter what, and not once the game is started.
I have used many tutorials on many websites to make this game thus far and feel i just have too much useless stuff going on. Ive tried to remove certain things but they all seem to stop gameplay. I have attached the source file to the game and hope someone will be able to shred any light on it. Thanks.
