Noob questions on Steam version and NVidia 3D Vision

[Gapper4]

Greetings Ladies and Gentlemen,

Hungering for something more substantial than arcade flight sims, I've recently taken the plunge and bought the Steam version of IL-2 1946. Trouble is, it doesn't patch up to 4.11, only 4.09. I've tried patching manually but now the game doesn't start. Does anyone know if Steam intends to eventually patch or if there's a way to do it manually ?

Also, and perhaps more importantly for me, NVidia's 3D Vision doesn't want to start with the game. I've set it to DirectX and Full Screen but so far no joy. Is there a trick to enabling the 3d ?

Thanks in advance for any replies !

regards, george
