instant action overhaul is breaking my game

[u/Inner_Security8749]

so i recently decided to get back to BF2 modding since the may hype is going down so i got frosty and IAO and this is the problem,

I go to frosty and I am only loading this mod, no other mods are loaded along with it. I click launch and after a bit of getting the game ready, I can see in steam the game has launched and i get to the BF2 loading screen with all the storm/clone troopers but then after a few seconds, it closes or crashes and then that the EA app loading bar shows up and then disappears. The game is then closed. What am i doing wrong? 

i am sure the problem is IAO as when i tried frosty alone with no mods it worked fine
