PiFace Display and control 2 seems not working on Raspi B+ model

Question

Just to know if someone has already experienced this kind of issue:

Last update raspian on PI B+
PiFace Display2 tested on the device (works fine on PI 2)
Camera
All the other parts works fine

Instead the display is 100 unresponsive and when I launch any test from the command laine I receive a message of "internal error" and the program stops. Nothing is shown on the display.

If someone has already experienced something similar and has some check / test to see what maybe wrong (sure it is software) let me know.

Thanks in advance.

If you have a card working with RPi 2 and Piface 2, do not use the same sdcard for the othe combination pg B+ amd Piface 2 because of Anyone got PiFace Control & Display 2 working with RPi 2 Model B?

The reason is "A5 Device Tree - which I disabled", needs to be re enabled.
