The samples included in my attachement work fine for me. Be sure to run the touch calibration sample first to see if you need to recalibrate the touchscreen.
Here try this modified library. It's working great together with my Uno R3 and this lcd tft shield.
I also have a question for anyone that also has this shield. I need to free up a pin. Which pin would be easiest. I don't want to destroy the LCD TFT by outputting 5V to some part I shouldn't.
