I also have a problem, I could be a glitch with the diff_fm file ? Here is the end of my log file:
sFMDir = gui/game/buttons
[14:15:11] s1 = flightmodels/ju-88a-4late.fmd
[14:15:11] s = FlightModels/Ju-88A-4Late.fmd

Perhaps a problem with "_", as the air.ini line is :
Ju-88A-4_Late air.JU_88A4_Late 2 g01 WINTER
(does not work either when I change the Ju-88A-4_Late to Ju-88A-4Late). Hope it will be sorted.
Nice work by the way Karabas-Barabas
. Improving existing aircrafts adds great value to this game.
