gzip: stdin: invalid compressed data--crc error

Appears that the file is corrupt.

Please issue the following as well

tar tvf example.tar.gz

See what you get

You can also try with

tar tvfz example.tar.gz

But I think the tar archive is corrupted

Another thing.

Please try this
gzip -d file.tar.gz
and then do
tar -xf file.tar

No Luck
$ gzip -d examples.tar.gz
