But the ZIP file of the testdata seems to be broken (cannot be unzipped, no end-of-file signature is found which is important for ZIP files). Got the upload perhaps corrupted? I tried on different machines.
Hello. Thank you for your interest; it seems the archive file is corrupted. We try to fix this as soon as possible. Meanwhile, you can try the 7-zip tool, even if it gave errors, it unzipped the file for me.
