Hmm, it seem you ran the game via IL-2 Selector.exe - which I never did until now.
That apparently reverts dinput.dll.
If I run il2fb.exe directly that doesn't happen.
But I guess you would run into the same problem as SAS~Storebror.
I'm investigating the problem.
The paths are correct - I can explain it later.
BTW: yes it's suitable for modded games - I'm running it with VP Modpack
