Video won't save!! :( – SquArea - Post Entire Videos with Border and Text for Instagram Review

I upload the video into the app and it will frame the video with the white boarder but when I click the export button nothing happens:( it just says "processing" and after that nothing happens. Please fix that! I love how this app doesn't have a watermark!
