Failed to install client on linux

I got the error as below:

==============================================

 ./ccollab_client_6_0_6013_unix.sh

gunzip: sfx_archive.tar.gz: not in gzip format

I am sorry, but the installer file seems to be corrupted.

If you downloaded that file please try it again. If you

transfer that file with ftp please make sure that you are

using binary mode.

==============================================



After I downloaded the .sh several times, I still encountered the same issue.

And I find from line 413, there are lots of unreadable chars.



Would you please help to invesigate this issue?
