Apani VPN

Does anyone know if the latest version of Nortel Apani VPN is the following ?

Apani Version 3.5
Apani Build 043D.20070207.1310

When I download it (as a licenced owner) I seem to get a lower build number and it says v3.5 2006 instead of Feb 2007 ?

I am having problems with it disconnecting the VPN connection after 10-11 minutes or so.

thanks
