Twonky Missing from MBL

As the title says, I cannot see any Twonky option for the Media Server…  

Firmware:

MyBookLive 02.42.03-027

I only have the DLNA and iTunes option.  Is this a change with the firmware.   I purcased this drive yesterday and the first thing that happened was a firmware update to the latest.

Newer MBL’s ship with WD’s own DLNA server, but it’s possible to swap it with Twonky.  Check the Knowledgebase for instructions.

Quick look for it and I can’t seem to locate it.  Maybe I am looking for wrong keywords.

Here it is:

Thanks, 

This site helped.   http://mybookworld.wikidot.com/forum/t-459592/complete-guide-to-upgrade-to-twonky-7-version-my-book-live-o

Have it running now.  I bought the server.  Seems to work better then the native DLNA one.
