If I believed the error messages, I would assume that the file has been truncated and possibly download it again and check its md5sum before loading.

Hello Michael,

Thank yo for your suggestion!

I should double check the size of the file. It should 67.5MB, not 37MB.

Thank you again and really appreciate your great help!

Best regards,

Yue
