Have you done the simple stuff too?  Booting into Safe Mode, holding 
down the Option Key to start from a different OS (or even the main OS)?

I had similar reboot problems... but I have multiple partitions I can 
start up from.  I just picked another one and ran DW 5 from there.

For a while, I needed to hold down the Option Key to pick my main 
partition.  It would start ONLY when I used the option Key... just a 
restart would result in a hangup.
