Adobe connect audio cuts out half way through my recorded webinar.......Please help ASAP

I am a trainer and I record webinars for my students so that if they miss the face to face classes, they can catch up by listening to the webinar recording. I recorded a webinar that was just over an hour long, then after 29min and 40sec, the audio just stops all together. The green mic stayed on the entire time that I ran the webinar and one of my students just brought this to my attention today. Please help........
