I have a project that is corrupted. The preview screen only shows black, and all my clips disappeared when the mouse scrolled over them. The timeline says to click and browse for photos/videos, but the preview screen displays the duration of my timeline as if videos are there. This has happened before and someone fixed it. Last time, I think it was because some of the in and out times were negative or incorrect. I have a deadline to meet and would truly appreciate assistance. Thanks !
