Scrobbler not reading iPod

I recently got a new computer and the scrobbler won't acknowledge that the iPod is even plugged in. I have had a lot of issues with the scrobbler in the past, but I'm hoping I can resolve these with a new computer, but it doesn't help that it won't even recognize the iPod. What can I do?

It is really strange. I wish last.fm would help us. I uninstalled and reinstalled it and still no dice.

this just worked for me:
clear the user associations in last.fm as said above.

-plug in your ipod
-click music (under your ipod logo)
-right click the top of one of the empty columns, ie: (song name, artist, album) to the far right. Make it so last played and play count are options
-click last played so that the most recent stuff played on you IPOD is at the top.
-play the first song at the top, then move your mouse to the 0:01 second mark and click it.
-if you do it right the play count should go up.
-keep your mouse over the 0:01 second point and keep doing it so that last second plays and your ipod considers it scrobbled.
-do this until you get to the last song that wasnt scrobbled from your ipod.

Note: since you altered the play count within your ipod, it will be like you listened to it. The date when you listened will be wrong, but the info will still be there, which is what i care most about.

NOW:

eject the ipod
close itunes
close last.fm
restart your comp

I left my ipod plugged in, but if u want to take it out it prolly doesnt matter.

Now when the comp starts up plug in the ipod, or if its already in wait for itunes to load up.
last.fm should show up too.

if it scrobbles what you just did automatically, problem solved.

if not, open the last.fm box, go to options>diagnostics>click scrobble ipod.

you may need to do it once with "itunes automatically scrobbles... or "i manually.."

mine is a 160 gb ipod on windows and I did the manual setting, then clicked scrobble, and it picked up all the songs that I just went back and manually "played"

Worked for me.

Peace and good luck.
