Sonar Platinum & Dmxis as a plugin

Hello I've recently purchased the Enttec Dmxis hardware and software, all are 64 bit

I've got a handle on making banks and presets in the stand alone, but when I try to write a bank in Sonar using the piano roll view everything will crash everytime when I try to write on note C0 which is bank 1 in Dmxis
I've followed the "How to use DMXIS in SONAR X1" method

Anyone?
Thanks
Ray
