Cannot Open Storyboard Pro Project

Recently I exported my Storyboard Pro project in three different file types: .mov, .pdf, and I exported to Harmony. However, since I did I can no longer open my project in Storyboard Pro. It doesn’t show up under recent projects, and when I do open the file location and try to launch from there, it shows a message saying asking to choose an application to launch this. I try selecting Storyboard Pro, but the executable is grayed out and won’t let me select. Has anyone else ever encountered this problem? I’ve tried opening it in Harmony and it won’'t let me either. Also to note, I haven’t move any of the folders or locations of the project ever.
