Why not update my ipod touch work?

Is the iPhone 3.1.2 update. every time I try to leave is completed loading, and theres this sign will say: "It is an error downloading this. Make sure you are connected, or try again later." Well, I tried again later and nothing! Please help! Indeed, my first generation iPod Touch is one. And my iPod is connected to my laptop.

Not try to update it for several weeks. Now I'm back to my iPod touch second, because he died after trying to install the update itself. So if you are prompted to say no.
