Trouble with the FMC Flight Planning

Hi, I was just watching a FSXGenius video on how to pick sids and stars and he was using Flightsim commander, So I downloaded it and used it with VATroute to plan my short flight from LFPG to EGLL. Using the winds data and the runways I managed to make this route: LFPG OPALE UT421 KESAX UT426 DIMAL UT10 ALESO EGLL then I chose SID OPALE3D and STAR BIG3B as it appears to start from ALESO on the map. As the star ends at BIG I need to use transition BIG to get me to the runway in my case is ILS27 or could be ILS28 but when I enter all of that into the FMC, the BIG transition does not show. I'm sure I have seen it before. Have I done anything wrong? Also I think my nav data is out of date it is from august/september 2013 I think. 

If you need me to provide anything else I can.

Thank You.
