Using Qjackctl to connect Hydrogen drum machine to Ableton Live 8 Lite.

Hello! I have a small request for help on something I've been working on these past few days.

I want to be able to use Hydrogen as a drum machine in Ableton Live 8 Lite and connect it via Qjackctl to send the output of Hydrogen to a channel input in Ableton. I downloaded and installed Qjackctl and have the window open and ready, except that whenever I press Start, it gives me the error message:

"Could not start JACK.

Sorry."

and this code message:

12:24:00.596 Startup script...
12:24:00.597 artsshell -q terminate
Cannot connect to server socket err = No such file or directory
Cannot connect to server request channel
jack server is not running or cannot be started
sh: artsshell: command not found
12:24:01.000 Startup script terminated with exit status=32512.
12:24:01.000 JACK is starting...
12:24:01.000 jackd -dalsa -dhw:0 -r48000 -p256 -n2
12:24:01.015 Could not start JACK. Sorry.
12:24:04.038 JACK was stopped with exit status=255.
12:24:04.039 Post-shutdown script...
12:24:04.039 killall jackd
No matching processes belonging to you were found
12:24:04.445 Post-shutdown script terminated with exit status=256.

Could anyone help me or give me any advice? Either so, if there's a way to connect both programs without so many roundabouts, I'd love to read any suggestions, but please explain to me in as much detail as possible. I'm still a bit new to using audio this way.

I'm using a MacBook Pro with OSX 10.10.2 (Yosemite).

Thank you very much. Hope to get a response soon! :)
