The statement I refer to regarding copyrighting your files is the first sentence in the EULA, which states:

Curious Labs, Inc. (Company), a California-based Corporation, provides the computer software and associated prorietary file formats (Program), and accompanying documentation (Documentation) in this package and licenses its use.

Emphasis mine.

If the proprietary file format is being licensed to you, not proprietary files, but proprietary file formats, which means any file in those formats, regardless of content, how can you own your files? The format belongs to CL, so the file belongs to CL, right? Or not?

Other portions of the EULA support this notion.

Like I said, I hope I'm reading this wrong.
