It works when spawned in. Maybe, your keybinds are different. If you are using Japanese keyboard, or a Mac keyboard, key codes tend to differ.

In addition, you need to hold the Armour in your hand to activater it, not wear the armor (counter-intuitive, I know). Maybe that's the issue?

Finally, the next time you have a question, may I direct you to the forums?
