If you mean the Intro movie that plays when you start IL2..
Run the il2set.exe program in your game folder:
C:\Program Files\Ubisoft\IL-2 Sturmovik 1946\il2set.exe
There is a 'Intro' checkbox in the bottom/left corner that you can uncheck to turn that intro movie off.

When I clicked 'Pledge Now', I expected the screen to change and say congratulations or 'your registered' or something, but it just sat there...
But I did just receive a confirmation email, so I must have worked....
I love my firefox browser.
