MIDI disapeared and won't come back dont matter what I do.

I lost MIDI. I use Native Instruments Komplete Kontrol S49 (not newest one). The USB MIDI was working with no issues. I been testing some soft synths (load and unload them), and at some point i realized- I have no MIDI signal. Usually, it solved by disconnecting and reconnecting MIDI keyboard (I used to have to do it with Novation controller, but with Kontrol I did not have to do it), and restarting computer would most always solve it. But now- dont matter what I do- it does not come back. If I disconnect the USB cable, Sonar feels it and says, "You just disconnected device- would you like to re-route it to available ins/outs?" When I reconnect it, Sonar says, "new MIDI device connected- would you like to add it?" So I say Yes, but nothing happens. Kontrol is checked in Preferences/Midi Devices. It shows up on the MIDI track. I select it for input, press keys and have no movement on meters and no signal. Restarting Sonar, Restarting computer, changing cable and different USB port does not solve it. I do have movement on the little icon in Windows Tray when I press the keys but nothing on track meter. Any help will be appreciated. Thank you.
