BES Express 5.04 and Exchange 2013

We are migrating to Exchange 2013 and are currently running BES Express 5.0.4. According to Blackberry KB:
KB33406 this is supoprted but requires an "update" only obtainable from Technical support.

I have been trying for over a week to get the update from support. I have called and emailed each day with no help or response. Does anyone know of another way to get this file so I can continue our Exchange upgrade?

I have been told they are pretty responsive on twitter, maybe try contacting them there?
