Found the cause:

The cause was the licence evaluation dialogue. The dialogue text was not readable on my computer (see figure below) and the window was often hidden behind other open windows.


So I sometimes closed the window and sometimes left it open because I couldn't see it.
When you close the window, the ip core no longer works. - But how can you tell if the dialogue is'nt labelled?

I found the clue here:

Fig. Evaluation dialogue
