Adding the Touch Screen

I have a Panda and bought the screen. It was working very well but now I wanted to have the touch screen. Well that was bad for me. Its NOT working. I ordered the panel from DF Robots and Its not working at all and like an idiot already glued it onto my screen which is working.
Is it possible I missed something to get it to work?
I tired installing V1.1 drivers in Administrator mode and still nothing.
Help
