Error while extracting area_1.tar.gz (with XYZ)

Dear Stanford team.
Thank you very much for releasing your excellent dataset.
Your dataset will help us in our research in processing point cloud data.

However, when we extracted a part of the dataset, area_1.tar.gz (with XYZ), with the command tar -xvf area_1.tar.gz, we encountered one problem as following:

-------------- start of error message --------------
area_1/data/global_xyz/camera_531efeef59c348b9ba64c2bf8af4e648_hallway_7_frame_56_domain_global_xyz.exr
gzip: stdin: invalid compressed data--format violated
tar: Unexpected EOF in archive
tar: Unexpected EOF in archive
tar: Error is not recoverable: exiting now
-------------- end of error message ---------------

I have tried re-downloading the tar file from google drive and re-extracting it several times, but I could not extract it due to the same error.
Furthermore, I observed that the MD5 checksum of the downloaded file is different from the one you have published in https://github.com/alexsax/2D-3D-Semantics/wiki/Checksum-Values-for-Data. 
Is there any way to extract the file completely?
Thanks in advance.
