Howlin is right. The fact that all the same planes are failing... precisely the ones that came in 4.09m official patch release should have ringed you a bell "I forgot to patch to 4.09m"

"Installation Instructions for History Mod Version 4.0

1: Patch il2 Sturmovik 46 to Full 4.09m
------------------------------------------------------------------------------------------------------------------------------------
Detail : The History Mod version 4.0, requires an install of Il-2 Sturmovik 1946, plus Patches 4.08 and 4.09.
No other previous Mod Patches are needed. Version 4.0 includes all the Mods released from the beginning,
plus the new content for version 4.0.

Patch 4.09 - The IL-2 4.09 Patch is available at http://forums.ubi.com/eve/forums/a/tpc/f...9861059397
"

So, do exactly this: IL2 DVD + 4.08m + 4.09m + HSFX 4.0 + HSFX 4.1
