Zip file is corrupt

[vladmihociu]

I have 10 pages to be downloaded.

I have tried to download the first page 3 times, and all 3 times it downloaded different sizez (40gb, 11GB and aprox 40GB).
All 3 times resulted into a finished download of page1, but the zip is corrupted :(

I have changed the PC and now it ended at 1GB :)

I'm also getting it on a few files. For example:

Archive:  31_page.zip
  End-of-central-directory signature not found.  Either this file is not
  a zipfile, or it constitutes one disk of a multi-part archive.  In the
  latter case the central directory and zipfile comment will be found on
  the last disk(s) of this archive.
note:  31_page.zip may be a plain executable, not an archive
unzip:  cannot find zipfile directory in one of 31_page.zip or
        31_page.zip.zip, and cannot find 31_page.zip.ZIP, period.
