Comment (by Roland Haas):

Thank you. Glad to see that this worked. Would you also mind to update the web-page at (in the www repository to which you have write access): http://einsteintoolkit.org/gallery/poisson/index.html by updating the “This example was last tested on” date and the link to the current data set?
