Hello!
I'll set up a 10.2.2 machine to try out the sample and see if there is a problem with that release.
In the meantime, are you running with background GP (64 bit)? Or in the foreground (32bit)? If it is background, try turning off background GP to see if the sample works in 32bit.
The "interface not supported" part of your error makes me concerned that something broke in 10.2.2, so I'll try that in the meantime.
This might take me a bit, so if you need help more urgently, please contact tech support.
Thanks
