Internet DJ console won't start up.

[MachintoshCJ]

I can't get it to start because Jack Sound Server won't work. I don't know what it's talking about, and non of the tutorials are helping me. I do what the program said to do, but I can't get it to work still. Here is what is say:

christopher@christopher-EL1330:~$ jackd -d alsa -r 44100 -p 2048

Someone please help, because I want to start my own Internet radio station before I change my mind.
