Find an iTunes version for OS X 10.4.11

Dear All,

I restored an old computer which worked bad by re-installing Tiger, but I lost the latest iTunes version of my 10.4.11 version of this OS X.

Currently the iTunes version running on this Power PC G4 is : iTunes 4.7.1 (30), but I can't login my Apple account ID on it, I have an error message.

If I can ask another question, I lost my old version of iLife too..., I only found my two CD iLife 09 and 11, but not the first...

I try to up graded iTunes with the new version, but of course unsuccessfully.

So could I found the latest "old" version for this Tiger OS X 10.4.11, and, found somewhere the ancient iLife?

Many thank's for your help.

P.S.: I wrote this from my iMac 27", not the Power PC G4 which is not running with my Apple ID.
