The problem that I have just found is that the Kivy Pie1.0 does not have the kernel for the Raspberry PI 3 Model B+ - SPECIFICALLY THE PLUS latest Raspberry pi.
Run
sudo rpi-update
this updates the kernel for all models for pi and adds the kernel for the Raspberry Pi 3 Model B+ - shutdown and swap to the Pi 3B+ and it boots up.
if you have the official 7" screen with stand that displays upside down, you may also wish to modify the /boot/config.txt to append
lcd_rotate=2
Also note that the kivy does not have wifi by default and the /boot/interfaces file needs to be updated - as described in another post on this forum.
