Ableton Plugin not sending audio to main mix recording

UPDATE: It’s fixed by starting all over

I have unfortunately never been able to get the Ableton plugin to work properly. I see that it records signal on the sensor tracks in Ableton, but in the video, I see that it should also send the signal to the ‘main’ group. That is not happening. As soon as I press play, I don’t hear anything, even when I unmute the main group. However, I do have signal during recording. I’ve clicked around quite a bit, but I just can’t manage to get the recording to play back. Also, exporting the recorded audio results in a file with silence.

It’s so frustrating that I keep giving up, but I can’t properly record a production like this (which I’ve finally gotten around to). Unfortunately, my time is limited, so when I see a response with a possible solution, it’s uncertain if I’ll have the time to fix it. Don’t you have any one-on-one sessions or something similar? That would save so much time.
