Annoying unknown iTunes error?

[prmccarron]

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.

This issue usually happens after the iTunes 9.0.3 update. I haven't had the misfortune of running into it but the usual fix is tied to the SC folder or the iTunes preferences files.
