.tblk file doesn't work
Tunnelblick questions are better asked on the Tunnelblick Discussion Group (https://groups.google.com/forum/#!forum/tunnelblick-discuss).

The problem is that line 88 of your configuration file contains a reference to a file named "ca.crt" and that file is not in the "Empty Tunnelblick VPN Configuration.tblk". All files referenced in a configuration file must be placed in the .tblk.

(The reason the paths are so weird is because Tunnelblick is referencing a temporary copy of the .tblk that you are trying to install.)
