Hi all,

Not sure if I've got a problem or not with this.

I used Three Press validation tool and get the all-clear on the .epub file (I'm using Sigil). But when I try to validate the converted .mobi file (using Calibre), I get this error:

1. ERROR: The Red Cockatoo - Mitch Miller.mobi: corrupted ZIP header
2. ERROR: The Red Cockatoo - Mitch Miller.mobi: I/O error: error in opening zip file
3. Check finished with warnings or errors!

I've downloaded and installed the latest Calibre software and still get the same error.

I've attached the files here. Apologies they are quite big.

Many thanks in advance.

John.
