Is the first time I see someone relating this bug, maybe is due english.dll over Czech version...
Just in case:
Instal the game in original language, run STEAM update to the last official patch ("Loft" patch), the second screen show 1.11.203.62,
and test, before change .dll and add MOD patchs.
After, if want install Team Fusion MOD patchs (advisable), follow the order:
Patch 3.0
Patch 3.01
Patch 4.0
BTW - You are using DVD to install?
STEAM dont have the game in his account to download?
And man, Ju88 is sweet to flight, it's Kurssteureung work like a "clock".
