Sorry, but it's such an old version of Tunnelblick that I don't want to spend any time trying to support it.
There are ways to use older versions of OpenVPN with newer versions of Tunnelblick but it's not documented.
Copy the folders containing OpenVPN binaries
from an old Tunnelblick.app/Contents/Resources/openvpn
to /Library/Application Support/Tunnelblick/Openvpn
and they can be used as if they were built into the new version of Tunnelblick that's installed.
