When I try and open my project, there is no storyboard (just has 'Click here to browse for videos and photos' like when you start a new project) and when I hit play it is just a black screen, no audio or video. It still has the timer and shows the number of items in the project.

If I add a video then click undo, the 'Click here to browse for videos and photos' disappears and the black bar that tracks progress as you play appears, but there is still no storyboard at all.

It's not the first time this has happened, last time it did I just had to start over again which was incredibly time consuming. Hoping it won't be the case this time and I can find a fix!
