Akai MINI MPK - Editor won't upload settings to the controll

Hello everybody,

Got the Akai mini MPK connected and in function.

The problem is between the Controller and the Editor.

Created and saved my own preset.

But once I push the upload button, nothing happens. No ok window, no green light.

Same way, I can't get presets from the MIDI device.

I need to split the keys and the pads on two different MIDI channels.

Any idea on how to fix this?

thanks in advance fellas
