[Mongodb still won't work](https://i.stack.imgur.com/rofli.png)

I used brew to install mongodb and updated it and everything. 
I used [this](https://treehouse.github.io/installation-guides/mac/mongo-mac.html) tutorial to download and install. I was able to do everything listed but when I tried mongod it didn't work. I've had mongodb downloaded and working previously on my laptop but had to factory reset recently and now it won't work.
