CBZ to EPUB

[starbreeze89]

I have scanlations of manga that I am trying to convert into an ebook format. Most of this has worked well. Unfortunately, with a few of the rar files I am trying to convert, I get the error "ValueError:Could not find an ebook inside the archive" and when I click "show details..." it says:

Traceback (most recent call last):
File "site-packages\calibre\gui2\actions.py", line 1138, in convert_ebook
File "site-packages\calibre\gui2\tools.py", line 39, in convert_single_ebook

File "site-packages\calibre\ebooks\conversion\plumber.py", line 589, in find_html_index
ValueError: Could not find an ebook inside the archive

I have looked at the contents of the rar files and I cannot find any formatting differences between the ones that do and do not work. Any suggestions on how to fix this problem would be greatly appreciated!

Thank you for your time!
