Nyquist missing

I’m REALLY new to using Audacity and I have found that I am no longer able to open Audacity (I just reinstalled on my Mac tonight) because I was getting this message. I am trying to put together my first podcasts and so I am starting to think that maybe I am using the wrong program? Any suggestions would be helpful.

Mac OS X 10.9.1 is the version of my OS…

Thanks in advance…
