Two things:

1) Why not make a copy of the whole Rev app folder when things are 
working (or at least the revPreferences stack), and when things fail, 
just make a copy of that copy?  Shouldn't take but 20 seconds or so to 
copy the copy and have a running Rev app -- no reinstall needed.

2) I shouldn't say this out loud, because I'll probably jinx myself, 
but the only time I've had Rev crash on me at startup is when I did a 
"start using" on a stack that had an "on openStack" handler in it.  It 
got into some weird infinite loop that caused it to hang.  My rule now 
is that any stack that I call "start using" on must be a pure library 
stack -- i.e. it never handles any system messages such as "on 
startup", "on openstack", etc.

Don't know if this is what's happening with you, but you might look at 
the stacks you're calling "start using" on, and see if any respond to 
system messages.
