Most likely because the .opf file or one of the files referenced in it was invalid. I'd recommend creating an .ePub file with
Sigil. This has several advantages over hand-crafting an ebook:
- Sigil will automatically generate the .ncx file and all other required files
- You can test the validity of your book with Sigil's internal validator and
epubcheck.
- You can also automatically generate an HTML TOC from your NCX and add guide items for Start, TOC and Cover.
If your .epub file passes epubcheck it'll also compile without problems with Kindle Previewer. (Kindle Previewer will automatically unzip the epub file.)
