Lost "press e to start engine" and ordnance displa

Hi all,
I'm new to combat flight simulator 2, and when i installed it, played it. I used to get "press E to start engin etc".
That no longer shows up. Neither does my ordnance on pressing backspace.
Heading, speed do show up when pressing shf+Z, but not the others.
Tried reinstalling but no luck yet.
Any ideas anyone?
Ste.

you could read the manual and it tells you what all the keys do....that would be the smart thing to do also

I got it sorted.
Must have pressed D at some point, pressing shift D got it back.
