I tried that, but when I click the autosave version, the same message appears: "the file provided is not a valid Videopad project file"
Update - I managed to retrieve an older verson of the edited video. Although it's not 100% solved, I think this is the best I can do.
I was editing a video when my storage got too full and VideoPad crashed. Now whenever I try to open my project (the video I was editing), it says "the file provided is not a valid videopad project file". I spent so long editing that video! What do I do? Is there any way I can fix this?? Please help!
