Logic Pro 9 logic 9.1.8 hanging on startup in Lion 10.7.5


Hello To All,
I have been forced to move from OS 10.6.8 (SL), to 10.7.5 (Lion), because I need to use some new plugs that won't work in 10.6.8.
Logic 9.1.8 hangs up in 64 bit mode on this screen message:
Searching for Audio Unit plug-ins (Apple:AUNetReceive)...

I did not do a clean install. I was able to get logic to boot in 32 bit mode, but I can't go back to the audio bridge, I need to be in 64 bit mode.
I'm using Automap 4.7 with a novation 61sl mk2 controller.

Can anyone help me here?

Thanks in advance for your help luggers,

Best regards,
