Okay so this may sound strange but I was editing a video like normal. I was splitting clips when one clip, when I split it, suddenly turned my movie into a black screen and deleted like 10 clips and there captions. In the bottom left corn, where it tells you how many clips you have (Item 1 out of 17), it says I still have 17 clips when only like 8 appear in the timeline. I can't even watch the video. It's just a black screen with no audio. How do I fix this? Please help. I spent too long on this to redo it.
