No sound when I play certain keys, Key Out Indicator flashes, but no mappings set

Hi, I have a problem - I get no sound when I press two specific keys (namely the notes B and Bb) on my MIDI keyboard (M-AUDIO Code 49). All other keys work, but these two don't. When I play them, the Key/MIDI Out Indicator flashes (the orange one to the left of the yellow one that flashes when Ableton sends MIDI messages), so it seems like those two keys are mapped to some remote control assignment, but I've looked into Key and MIDI mappings and they're empty, there's nothing there. So I'm clueless as to what's going on. They work fine when I use other DAW, but I want to use Ableton.

I don't know how it happened, but I'm a beginner user, so I probably just accidently pressed something and don't know how to reverse it. I've searched a lot for a solution and didn't find any, so I'm asking here.

Please help, thank you.
