How did yaal instal Instant Action Overhaul XL Alpha?

I installed the merger and localization editor but everytime i try to launch with the mod it says:

"Access was ModData/Default was denied"

But i dont have a mod data folder? So am i supposed to create one? I dont get it, pls help?

Also one of the requirments is no longer available, so is there any way to get around that?
