K-1000:

I just tried with the Space unplugged and I could open H9 control, but as soon as I plug the Space into the computer it isn't recognized by the software and if I try to restart this last one (when Space is still plugged in)  it shows me the message "H9 Control encountered a problem and needs to close" again….

Well, try starting H9 Control without Space plugged in. A dialog will pop up saying "Device not found". Leave it there for a moment. Then plug in your Space.  And in the device not found dialog select the option "Manually select a device" and in that dialog choose the MIDI ports of your Space and add it. Does that work?
