Hi,
I tried to do my first epub but it appeared this message:
BASIC runtime error.
An exception occurred
Type: com.sun.star.packages.zip.ZipIOException
Message: C:/cygwin/home/buildslave/source/libo-core/package/source/zippackage/ZipPackage.cxx:773: Bad Zip File, ZipException: Zip END signature not found!.

And I do not know what can I do.
Can anybody help me please?
Thanks in advance
The ZIP file is corrupt.
I guess this means your Plugin download was probably damaged.

Tips:
Do not us an 'accelerator'
Make your Anti-virus ASK you if it want to fix something (so you know)
Hi,

you forget to say:
- LibreOffice, OpenOffice or what?
- what version?
- Windows, Linux or Mac?
- what version?
- what W2E version?

Moreover:
- have you installed the full package of Libre/OpenOffice?
- are you working with .odt files?

Finally:
- wish you send to me your original .odt file?
