The best thing you can do with that particular shield is actually throw it away.
Mine has never worked as advertised despite a lot of research.
IIRC there are a couple of other posts about that particular shield and those users also didn't get it working properly.
I went as far as talking to the developers who said it was incomplete.
Surprised it is still for sale !
Instructions or help online for this one is pretty much ZERO that is of any use.
Sorry about the news but if you want another one to match yours (its very dusty LOL) gimme a shout.
