Hello mister.
Fisrt, You must understand that there are 2 LED on the Cuhead. If you are using Uno, there is the North West green LED that is neer the power Jack of the Uno. The red LED is south east near beside Pin3 right north from the 2 jumper at the bottom of the Card. The green LED will never turn Red.
Second, have you downloaded the latest version of the librarie? The one name usercontribution? This is the one you must use to work with the Cuhead without headhake.
Third, You must comment and uncomment the proper option in the .h file name apps-conf.h, that you can find int the root of the folder Wishield in the library folder, so you get it to work with what you want to do. If you can't find the Wishield folder in the library folder, then you must drop a copy there.
Last, I can garenty you, unless you have blown you cuhead, that the shield does work. I made it work any way.
I don't know if this has help, ask me more specific question and i'll try to help you 
Have a good CupperTime
