iTunes unexpectedly Quits on start-up

[Don Linares]

Is anyone else experiencing this problem?
I updated to my OS to 10.2.8 from 10.2.6,
I updated Quicktime 6.0 to 6.4.
and updated iTunes 4.0.1 to 4.1.

Everything is working except iTunes, which quits at start up.

I've done it all. I dumped the preferences files, repaired permissions, 
and even dumped iTunes an re-installed.

Then I ran Diskwarrior and optimized the OS 10 drive.

No good iTunes still quits at start-up.

I'm looking to you knowledgeable folks. maybe someone here knows 
something, cause i cant find a discussion about this on Apples sight, 
and what ever is discussed goes unheeded by Apple.
