iTunes Error 42408 After 9.03 Upgrade

the first suggestion did it for me, but I wish it was the SC info folder because I have redo steps 1-5 every time itunes restarts or the computer restarts. Quite inconvenient.

Removing the SC info folder worked for me

Both of these have worked to some degree but I agree with other posts. It doesn't work if I restart the system and my ipod is plugged in on restart. Never a problem before. Definitely needs a fix or it will be quite annoying.

Hello all,

If you are experiencing the -42408 error syncing with a iPod or iPhone after updating to iTunes 9.0.3, please try these steps:

1. Eject and disconnect the iPod/iPhone from the computer.
2. Open iTunes.
3. Find a protected song from the iTunes Store (Kind = Protected AAC audio file) in your library.
4. Play the song.
5. Connect your iPod/iPhone.

Do you still get the error? If so, try these steps:

1. Carefully follow the steps in the "Remove the SC Info folder" section of this Knowledge Base document: http://support.apple.com/kb/TS1389
2. Re-authorize your computer: Store menu > Authorize Computer...
3. Sync your iPod or iPhone.

Do you still get the error?

Please report your results back here, and if one of my suggestions helped, let me know which one.

Thanks,
Roy

Tried both suggestions to no avail. I continue to get message asking me to sign in and authorize the account. I do that, get the message that this machine is authorized, and then immediately get the request to authorize again.

In addition to loosing access to my purchases, eventually
I also could not synch with my Nano anymore, although my other iPods were OK.

Solution; Quit iTunes,
delete file Library/Preferences/com.apple.iPod.plist
Restart iTunes and restore Nano
Reauthorize computer

Roy B, you're a gem. Followed the Apple procedure (http://support.apple.com/kb/TS1389) you suggested and voila, it works. Most grateful, really is a pain to be unable to access your music, films etc. Again, thanks.

Removing the SC Folder worked for me also... the first option, simply ejecting the ipod and trying to play the song did not work.

For me, too, neither solution has fixed the problem. Deleting the SC Folder started a whole process that required extensive reloading of my library (creating hundreds of duplicate files and deauthorizing a video that I had copied from digital video... and I don't have the code any more!). I hope Apple tech support is reading this and is working on a real solution.

I had the same issue with iTunes ver 9.0.3. I also could not purchase music from the iTunes store. What I discovered is that the automatic prompt to upgrade iTunes was giving me this problems. I had to go to the Apple iTunes page and download ver 9.0.3. Now I can access my purchased music, buy new music and I do not have that authorize/deauthorize prompt. Hope this helps.

I've tried every suggestion in this thread with no luck. It keeps bring up an old Apple ID that no longer exists. I've deauthorized and authorized with my current Apple ID, but when the error pops up it still has the old ID. I finally sent a feedback email to Apple.

This is by far the worst problem I've ever had with a software upgrade. Ugggh!

I was having the same problem with the -42408 error. Quite frustrating as some of these purchases are many years old.

I tried all of the different options that everyone has suggestioned with still no luck.

On a whim, I decided to make a change to my Preferences and save them, close iTunes and reopen it and...voila...I was able to listen to my purchased music again! Thrilled to say the least.

I thought I'd share this suggestion with the hopes that it may help someone else.

Thanks for the suggestion, but still no luck.

Is Apple tech support reading these? Hard to believe there's not a patch or any other response.

The simple solution - eject/unplug iPod, then open iTunes and play AAC protected song, then plug in iPod - worked for me. iTunes didn't automatically open, which was unusual. Incidentally, I can't find any such folder (SC Info folder) on my machine, so it's a good thing it worked. Thanks.

I was getting the same error, and I tried removing it from the dock and dragging it back in and it worked perfectly. Thank you!
