It is really weird. I use snow leopard with sibelius 6.2 and it works ok. But when I load the gpo4 (the latest version including Aria latest) it crashes. It is a preference configuration problem, because then I most trash some configuration files and plist files and restart everything to reopen any score.
I also try repairing the hd several times including with onyx but it did not work. I even reinstalled the complete snow leopard system and downloaded several times the garritan to make sure it is well downloaded but the problem persists.
Can any body help
