Apologies if you've already tried this, but I'd be inclined to hexdump
the working and non-working ZIP files and do a comparison of them. If
they don't start with the same stream of bytes then I'd strip down your
download script until it can send the first byte of the ZIP file without
corruption, and work from there.

cheers,
Richard
