OPF contains invalid tours section

[bravo.aevi]

Hi

I am new to this and tried looking up the error in forum and couldnt find any thing.

I have a html file, a ncx and an opf. I was able to use kindleGen to make a mobi file.

I am trying to use Calibre here. I put all 3 files above in a .zip dir and imported it in Calibre. When i selected the convert to epub option I get following error. Can some one help me understand this?

According to that error message your OPF file is empty, and calibre is using __MACOSX/epubExperiment/._product.opf instead, which wont work for obvious reasons. If you want more help, you need to post a complete example with all the relevant files that reproduces your problem.
