By "zoom in and out", I'm assuming you mean that, when you lean forward, your ingame view moves closer to the instrument panel. The only other thing I can think of is to check the TIR profile that you use for IL-2, and make sure all the 6DOF axes are checked. I think there is also an ingame menu you can call up and check that it is setup right, although I don't recall how to do that at the moment.

I also have to ask, if you just installed the UI, how did you get 6DOF in IL-2 before that?
