Map/Terrain textures don't load

[R4IDT3AM_ARG]

I'm having an issue with the Malvinas/Falklands (Op. Corporate) mod. I installed it in SF2I (Strike Fighters 2 Israel) but the terrain textures apear grey. I installed it in SF2 (base) too and the game crashed. I will test in SF2V (Vietnam), but i wanna know if it's a installation error or smth.
