Logic Pro keeps on crashing at start up

Question

I upgraded from Panther 10.3.9 to Tiger 10.4.2 on my iBook G4 1,33 Ghz. Now, whenever I want to start Logic Pro it just crashes. It does this each time. I tried disconnecting all my other USB devices, except the XSkey but that didn't help. I removed all Logic components and reinstalled the whole program. Again no success.
Logic Pro did work under 10.3.9.
What else can I try to use Logic Pro again?

hello,
even my built-in doesn´t work!! help
I have got a problem, while launching Logic Pro 7.1. It crashes at position "CoreAudio initializing"
I am sure, Logic crashes while initializing CoreAudio at startup because something is wrong with CoreAudio in Logic. I am sure, because I removed all Plugins, and, I started Logic with holding CTRL to ignore CoreAudio. Well this worked great. But after enabling CoreAudio (intern) in Audio Config in Logic, Logic crashes again, whilie trying to launch CoreAudio.
I am wondering, because few days ago, this worked great. I used the internal optical out of my Powermac G5.
Maybe this hint is useful: Standalone instruments like B4 from Native instruments work perfect, even I selected CoreAudio INTERN as Soundcard. So, only Logic got a Problem now with CoreAudio
Is there a possibility to reinstall CoreAudio? or refresh or reset it?
Thanks for your help!!
