unity web player has stopped responding

Every time i try to play family guy online unity web player stops responding completely, I have tried using multiple browsers each to no avail. I have re-installed unity web player about 12 times and no matter how many times i re-install it never works. I tried to play on another computer and it works fine, Why doesn't it work on my computer?

I can play any other games fine with no lag or connection problems what so ever, What the hell is going on?
