Make sure you install the mod on top of an unmodded 4.09 install. No other "MODS" folder with other mods should be present, and make sure the files.SFS is replaced with the one from the FH MOD. Best rename the present files.sfs, il2fb.exe, wrapper.dll (if present) and MODS folder (if present) and make sure to only have those from the FH mod active. Installing the mod files from FH Mod into an already existing MODS folder with different mods present will likely cause problems. Also make sure to install the mapfix that has been released after the release of the FH mod in this (http://forum.wbfree.net/forums/showthread.php?t=37201) thread. HTH
