I use the Generic Mod Enabler.

Do you mean JSGME? That is not a Mod Activator, it is a switcher.
What Mod Activator did you install:

ENG Sound MOD?
Primary Mod Activator v5.2?
Unified Installer 1.1 or 1.2?
HSFX?
UltraPack?
SAS ModAct?
???

Do you have an air.ini and buttons that include the aircraft you seem to be missing?
