Playback in Edit is black but playback in share shows video

Over the past couple of weeks, I have created a movie through Premiere Rush. However, I log onto my computer today and open the file to edit it, but all the playback shows is a black screen. However, I go into the share tab and it shows the video with all it's edits. I need help ASAP for this. I need this project done by July 14th.
