iTunes Error 42408 After 9.03 Upgrade

Mine will for no reason start working and within an hour or so then stop working.

Can't play movies - only some of the music that I purchased - I have some rented movies that I would LOVE to watch before they expire....

I would agree with the software comment if mine did not work at all. I am running a PC with Windows 7 - It works once and while and unsure why or why not. but most time does not work since the upgrade to 9.0.3.

Wouldn't you know it - for a moment it was working. I resynced my IPOD and moved the rented movies over to it before it stopped working again.

This is driving me crazy!@

I'm getting the same error message "50" on the iPod, iPhone and Apple TV....

To Roy B - thanks, but I tried both of your suggestions and still get the same error 42408. (My problem is not with playing iTunes music on the Mac, but with trying to synch my iPod to my Mac.) Neither in the pop-up menu that comes from plugging in the iPod, nor in the Store menu, am I able to authorize (or even deauthorize) my computer; I get that 42408 error.

Hmm, although Roy B's two suggestions didn't work, I then tried the suggestion of removing iTunes from the dock and opening it from Applications. That did let me (re)authorize this computer, and now things seem OK. Wondering if I can put iTunes back in the dock for convenience. Won't try immediately though.

I am now tearing my hair out. I bought my music through my AOL account, and when I tried to sync my iPod I first got the you are not authorised, so I created an Apple ID, and tried it that way. It doesn't matter whether I go via the old account to the new one, or just select the new one. It tells me my pc is authorised, or it gives me the 42408 error depending on how it's feeling. My music won't play on the pc, my iPod won't sync, but it lets me buy and play new music!
I can authorise and play a track, click on another to play that, then when I go back to the one I just authorised it again tells me it's not authorised.
I've tried every fix on here except the long complicated one I didn't really get, so I have:
- deleted the SC folder
-deleted and replaced the iTunes icon on my desktop
- deleted all my playlists
etc etc
Nothing works.
Does anyone know anything else I can try? Please?
Thanks

yes, but the problem is that when you restart the Mac, the old settings come back into play and our old friend 42408 comes back to haunt us:-(...so you delete SC info, re-authorise and it's all great, install some more updates, restart to complete the update installation.......delete SC Info, well, you get the drift of things......

this worked for me. thank you so much!

I tried this, it worked for me.

Thank you.

I do not have the SC Info folder on my computer. Please help...

The first steps didn't work for me, but when I went to the link that was listed and followed its directions...it worked!! 🙂 Thanks! 🙂

When I see this problem, iTunes attempts to re-authorize using an old iTunes account name I no longer use, which does not match my current iTunes Store login.

Some ancient Prefs plist or cache file is involved... Now to figure that out and remove it...

The only thing that has resolved this problem for me is to completely uninstall then reinstall iTunes. However, I've had to do it three times now. After reboot, I've lost authorization. I've determined the culprit is, indirectly, my iPod classic. If it is connected to my computer when I reboot or launch iTunes, iTunes loses authorization and cannot get it back. So there is a bug between the software and the device. Removing the iPod then plugging it in after launching iTunes gets everything working fine. Hope this helps someone else.

For me, the problem is recurent.

I have no more time to waste trying to solve it.

So, I am waiting apple's patch.

But in the meantime, I went on the store to report the problem.

You can report problems within your purchase history pages in your account.

Good luck
