Akai MPK Mini 4 and cubase 15 Midi script and mapping

I have just purchased an Akai MPK Mini MK4 for my laptop setup running cubase 15 pro and have installed the script and gone through the process of assigning cubase commands to buttons but it doesnt work, the transport play pause and record doesnt work the keys and the pads do but thats about it. I generally have always used my keyboards just for the keys and pads and not done anything too funky with other keyboard setting and if i ever wanted to assign a rotary knob to an instrument parameter i would just right click and learn cc so i am a bit simple minded in terms of midi setup. Does anyone know of a simple intuitive you tube or link for this setup or does anyone have any advice on what i could be overlooking. I have used it on my ableton live and all features worked out of the tin Thank you
