Logic Pro 8 Crashes from Core Audio - Tried Support Info

Question

This is my first question but I've been a Mac user since 1993. I have a MBPro 2.16 with 2GB ram. I have Logic 6.4 installed and it has been working well with the USB dongle. My factory HD was only 100GB so I just upgraded to a 500GB hybrid drive. I have Logic Pro 8, NI Komplete 5, Sampletank 2XL, MOTU Mach 5 and several other plugs that work fine on my G5 Dual 1.8. I upgraded the HD on the laptop so my Logic setup couuld be portable for use at my job as a band director.
I installed the new HD in an OWC external case. I started with a clean install of 10.5. The laptop still had the latest version of 10.4 (11?) as the OS so I wanted to start from Panther. After the fresh install of 10.5 I restarted from the external drive and had my settings transferred to it. Everything worked fine with either drive as the startup device.
I then installed all my music software from the original DVDs ending with Logic so it would see all the plugins on it's initial start up. I then ran software update several times until no new updates were found. I had no problems registering the plugs or getting them to work independently of Logic. I then transferred the new drive into the MBPro as the primary drive.
When Logic starts it crashes when Core Audio is initialized. The program never did authorize a single plugin as i never makes it to the setup program.
I have:
1. Started Logic with the Control key and it works fine (with no plugs or driver functions). The support documentation offers that help but does not specifically mention what to do afterward to get to full functionality.
2. I have tried to access the Audio Units Mamager in the Preferences but noting happens when I select that item (Tried many times)
3. The Support documents mention a key command that will select the AU Manager but there are no keys assigned and the Key Commands window will not let me add any so forcing Logic to initialize Core Audio has been a bust.
4. I noticed the mention in one of the support docs that there might be an issue with the language selected and made sure engligh was at the top of that list.
5. I have removed all the plugs from the library folder and tried to start without them to test for a conflict with one of the plugs.
6. Today I tried reinstalling Logic (over the old copy) with no change.
I'm at a loss of what to do next. Does the Core Audio need to be upgraded somehow seperately from the OS? Could the old version of Logic be causing problems? I've tried starting the 6.4 and it hangs at the Initializing Core Audio also when started from the new drive. Could the Hybrid drive be an issue? Thank you in advance for your help.

Pancenter - You hit the nail on the head. I had not heard about the Rewire conflict. As I was installing all of my music software I discovered a Digi/Avid extras disc that came with my Digi 003R. I had not intalled that originally when I installed Protools LE so I went ahead and added it as I upgraded to Protools 8. I believe the Propellerhead software came from there. Removing those files freed up Logic. Everything verified/loaded properly except the MOTU Mach 5 and all of my Bias Peak plugs. I belive the Bias plugs work fine with my G5 in my home studio but I use those more for mastering than music creation so I may not have needed them in Logic. I will troubleshoot those in the Macbook tonight. Thanks so much for your help.
