Corrupted ZIP header!

Hi folks.

Really enjoying Scrivener, and have a generated a nice looking eBook out of it.

However, when I post it on epubcheck, I get these errors:

Type File Line Position Message
ERROR -1 -1 Corrupted ZIP header!
ERROR -1 -1 I/O error: error in opening zip file

I’ve googled and only found this thread, which makes no sense to me.

phpclasses.org/discuss/packa … /thread/7/

I’ve searched this forum, can’t find anything about this.

Can someone enlighten me…?

Cheers,

Gavin
