No Midi in Ableton live lite 9

[Raymos]

Hi, I have a big problem with my ableton live lite 9. I have a launchpad S and M-Audio oxygen 25, and when i go my ableton, or magix music maker, it recognizes my devices, but when i press on a button, no midi signal comes, the little square stops blinking. When i go to preferences, my midi ports are on yellow/orange. I can't do nothing, please help me, I need help !! Thank you for reading me.
