I downloaded Lithians nature of the beast mod, and it says to press the V key to open menu. Nothing happens, i try to equip My Black Heart but it says i cant equip it. Any suggestions?

I can not help you with the problem you have, but i can tell you that it is not needed to make two different threads for the same mod. Stick with one because i am certain that a moderator will close one of them.

You are correct.
