Can't Start JACK

[doppel.ganger]

Hello,
My desktop's old speaker just died, so I got the idea of using my laptop's speaker temporarily using JACK and QJackCtl. I opened it and went to connections to attempt to route my computer's audio from the mic input to the laptop speakers. However, no connections showed up. I haven't used Jack in a while, so I assumed I had to start JACK first. When I tried that, I got 2 error dialogs saying the JACK server failed to start. Here are the logs:

Does anyone know how I might get this working? Any help would be greatly appreciated!

Thanks,

I think it might have something to do with the 5th line in the log, but i'm not totally sure.
