For some reason every time I open the movie in Premiere Pro, one of the shots says 'media offline', and asks me where it is. I then told the program where it was, but it still would not come on. I then re-imported and re-edited the cut back in. I closed it for the day, and have no re-opened it, but it's the same thing and will not locate the media, even though I told it where it is. It says it did after I tell it, but the media is still offline again. I haven't changed the name of the file this whole time, so why does it refuse to accept it?
