Livid base send midi data but no sound

Hey guys I'm a new livid base user in ableton, I notice when I'm using the keyboard mode with a synth, suddenly the sound stops for that track but the midi signals are still going to the DAW , after that I can't use any type of midi controller or my pc keyboard and have to close and open the project again, this only happens when Im using the Livid Base, I also got ableton push and this doesn't happens with it.
