Docker doesn't stop updating Volumes

Hi Experts,
I just downloaded the Docker Toolbox and Kitematic and nothing works.
I followed this tutorial and have a problem at Step “VIEWING THE WEBSITE DATA IN FINDER”.

When i click on Volumes to check the volume folder the image changes it’s status to “updating” and does never stop. Specifying a local folder in the setting does the same. How can i make this work?
When restarting Kitematic and starting the Image i also only get the same starting screen from nginx.
I downloaded the Docker Toolbox today but don’t know how to find out the version i’m using. Kitematic also doesn’t tell me the version.
Also i can’t upload images which makes it hard to communicate my problem.
I hope anyone can help me
