man something really not good is happeneing. I cant get any
midi deice to work and the audio/midi setup says if a
installed a new driver to get rid of it and try again
(basically) and the bad thing is now no programs will open
either. I have a mac G5 always stable the two most recent
things I put on here is a n rme 400 wwhich was fine. I also
have among other thing tascam `884 , I did something today .
I was using the rme 400 lightpiping the 1884 inouts and when
I sdisconnected  it now I cant open and well I said the
problem up there.
With out getting too deep in the things I did today on my
system , maybe someone can give some advice on how to get
back up
