FYI- apparently, noone can get this other app to run without crashing. My arc version of dual n-back has not yet received any error reports and so is hopefully working OK for people.
I can't get it to work because the sound functionality relies on Linux (and specifically, I think, KDE); I'm on OS X, and (a) I don't have the "play" command (well, I do, but only because I have TextMate; it's nonstandard), (b) I don't have a "/usr/share/sounds" directory, and (c) if I did, I still wouldn't have sounds such as "KDE_Beep_Beep.wav". Other than that, it appears to work.
Ack, I missed that :) It's a pity, though, as it's almost not. I'll probably tinker with that line to make it work on my machine, and that should be all it takes. Ah well.
