Ok, I just plugged in my old iPod (a nano 1g) and iTunes said I need to authorize my computer or 15 songs would be taken off. So I chose authorized, typed in my password, and it gave me unknown error -42408. I tried again a few times with the same results. So I decided to look it up on Apple's support website, and it didn't have anything about it. I also couldn't find it on Google. What the heck does this mean and how do I fix it? Btw I just plugged it in a week ago and it worked.
