I downloaded the magic mod recently, but I am unable to use spells. I have both IntFramework and MPW Library installed and active with the mod, but when I use the Special Activation key (H, I even double-checked it was the right key in settings) on the limb that the spell is assigned to, it does not activate. I've tried changing the SA key but it didn't work. Also, the H key is not assigned to any other control. Does anyone know how to fix this issue?
