Please provide information about the version you are using, your usage of the component (where exactly do you add it and how do you start/stop the progress).

I think this is the same of issue #27, I will assume that you are moving between 2 routes and you got this error. this is because you added the progress bar in a child component.
put the <ng-progress></ng-progress> in your root component template. NOT in a child component that can be destroyed
