Can't get Easychart contentype to work.

I Installed Easychart and necessary dependencies (Entity Embed, Embed, Libraries Api)
I copied files and directories of Highcharts-5.0.4 to /librasries/highcharts
I got Easychart in /configuration/media.
I can try to add content as Chart.

When it really gets clear it doesn't work.

- I tryed to save and got the message: "Please create an Easychart chart before saving"
- I tryed the Chart-button but there are no charts available
- The button Toggle Fullscreen doesn't do anything.

I am stuck.I don't know what to do.

These are the issue i received in console.
