Hi jsaw,
It took too long to download the OSM foortprints.
This is usually caused by the temporary bad connection between your computer and OSM server.
This happened several times to me.
Could you give it another try, usually this problem goes away automatically?
Another solution is to set footPrints='Microsoft' to use Microsoft footprints.
Let me know if this works.
