Docker not responding when starting WebODM!

First I get a message, "Docker is installed, but is not communicating… Launching docker…
Second message, "Fatal Error - failed - exit status 1
Third message, I Get a message, “We had some issues launching docker. Find the Docker application and start it manually, then restart webODM Manager.”
So I did that, but the forth message, “Fatal Error - failed - exit status 1”

Not sure what is going on here, I have several maps already accomplished on webODM, had Docker and WebODM for about 2.5 yrs. Please help
