Sustain pedal does not work

My sustain pedal has stopped working suddenly. My M-Audio oxygen 61 midi still works fine but the sustain pedal does not seem to be sending any signal anymore. I downloaded an external application to see if the computer is getting any signal from the sustain pedal. It does recognise the sustain pedal, so the problem is within logic. I found out that when I bypass all control surfaces the sustain pedal works for some reason. I also created a new account on my computer and opened logic on there, and everything works fine. I cannot find any setting I might have accidentally changed, that makes my sustain pedal only work with the control surfaces bypassed.
