Where are the iTunes Authorization and/or Documentation files on my Mac?

I have a Mac Powerbook G4 PPC.
I recently replaced the hard drive and everything is GREAT!

But iTunes is not great.

I was running OS X.3.9 and iTunes 7.something
I upgraded to OS X.4.11 and iTunes 9.2.1

I cant get the authorizations to work. There is always an error.

I emailed Apple and they gave me the runaround and then sent me an excited message that they have solved my problem! All I have to do is upgrade to the latest OS and iTunes! No Problem!

Except: Problem.

This is as high as this machine will do well. It was working fine with the Apple store before, and so I thought I would pull the authorization files from the old hard drive and put them on this - is this possible? Apple hasn't been much help.

Does anyone know where they are? In which folder?

Can you deauthorize the computer through iTunes? Then authorize it again?

Alternatively, back everything up (copy your Home folder, minus the Library - just Documents, Music, Pictures and Movies) and wipe the bugger (boot from an OS X install disk, quit the Installer, then run Disk Utility to format the drive). Then reinstall from scratch (run the installer on the newly-reformatted drive).

After running all available OS updates, open iTunes and authorize the computer with your Apple ID. After authorization all your purchased media should play again just fine.

Nope - that is the problem. It is always the message that a "required iTunes component is not installed" and gives me an error of "42404".

What you suggest is the second and third thing I tried to do, but no dice: same message.

That is why I thought that there was a file or two that I could copy over that would make Apple recognize this hard drive as if it were the old one.

Have you tried stuff in here.

I am suspecting the upgrade (duh!), specifically I think you broke Quicktime in some way. Try installing 10.3.9 again, does iTunes work there? If not try to get that working first.

I'll try the reinstall again and use the tips they give in that thread, but everything else works perfectly in iTunes - I can play all of my unlocked music, access my Apple/iTunes account (see it and change information), play videos both in iTunes and off. It really is just the authorization that is a problem.

Luckily I also have a new iMac, so I can do a round-about with the authorization through that and load the stuff up on the iPod, but it is just too big at 27" to use as a portable. :)

Thanks guys. If anyone knows the specifics of the folders and files, let me know. I would much, much rather take it apart point-by-point rather than all of the install/reinstall business.
