OOPS! It looks like a serious crash on the way.

I hope you did enable time machine and you made a complete backup of  
your files.  I have been in that situation before, and the best way to  
get rid of all kinds of issues is to make a clean install of 10.5 with  
your original disc.  Then, use the migration assistant, that imports  
your time machine data.  It should do the job.

OR: you're using the firestudio alongside with an external FW drive  
and you're starting up on that drive, too.  Many FW audio interfaces  
don't like that.  I used to have the exact same problem in the past  
with 2 different FW interfaces on 4 computers (G5, PB17, PB15, Macbook  
13").  By all means, avoid daisy-chaining hard drives and audio  
intefaces, although multiple connections allow that in theory.
