Spent 9 hrs creating a slideshow that I saved. Closed PSE 11 and reopened and can no longer find the slideshow. When I select Find, Media type, Project, nothing appears, but there is a gray box in my grid that says "File size too large". Is this my slideshow and if so how can I recover it? I am sick as this was a large time investment for my daughter's wedding which is very soon! Please help if you can.
