"There was an issue communication with the cmd server.Check to make sure you have the latest version of cmd installed."

I had this issue and I resolved it by running the sencha CMD server. I was able to start it up using the instructions from: http://www.ladysign-apps.com/developer/use-the-sencha-cmd-webserver/#.VHGF5dKUdAo.

I imagine there is more info on this in the Sencha documentation but this seemed to make the error go away for me.
