UTouch Library is not working

Hey guys

Recently I bought a 3.5'' TFT Mega Shield:

I run the UTFT Library's example code on the lcd, and they worked, but when I run the UTouch example and touched the screen, nothing happened.
What can I do in order to fix that?
Thanks for those who'll help!! :slight_smile: :slight_smile:
