- I was able to use the 5 minute set up Bluehost provides

Hello - I was able to use the 5 minute set up Bluehost provides to start my first wordpress website. I was also able to install the WPMU Dev Dashboard. Now I am trying to install my first plugin. These are the steps I am following to do that:

1. Click on WPMU DEV in my wordpress admin panel
2. Click on Plugins
3. Click on the "Install" button under the Plugin I would like to install (appointments+)

I get an "Error - Install Package Not Available" message.

Thanks in advance for your help!
