What is happening to me is that I was making a video for maybe a month, I alredy finished and I was planning to export it, but suddenly when I open it the audio was gonne. Everything looks normal but with no audio. When I press the play botton, it says: One or more clips of your sequence still processing. You will not hear this clips until processing finishes. But the processing never finishes... I am scare that I lost the hole video, what can I do?
