Nah man, it was like a video editor of some sort. Not Youtubes "download" thing or "studio" thing either. Like it was so cool . I immediately regretted pressing the X button on it but then it was too late.
Or Im not even sure if it was a video editor, but my limited experience with them makes me inclined to think it was.

This is the most unpleasant thing that can happen when creating a site, not counting completely reversed or lost code.
Unfortunately, however, there are no laws now that protect your copyright. The only thing you can do is argue with your competitors and ask them to delete their site or design. As proof, you can show versions of the site, screenshots, pages, and correspondence with the designers. I think good designers or design teams always keep files about the previous website makeover because it's important to keep it in the archive in case of data loss. I believe this is a professional approach to website development.
