Cubase AI5 quit unexpectedly

If I like to add new external midi device like GM or XG, system allow me to do this but during I make choice of instrument, Cubase quit unexpecedly and I loose all previous data. MAC OS 10.7 Lion is fresh after reinstallation.

Konstantin: Are you saving your Projects before
Recording anything :question:
If you have a CRASH Cubase will make a Backup.
But you have to save it first :wink:
