Magic bullet looks black screen

My Magic Bullet Looks plugin used to work fine and now every time I add looks to my project the preview becomes black but it just happens with that effect (I don't pay for mbl btw, they are crack versions). I've uninstalled and re-installed it many times with different ones and it always happens the same. In maxon, it appears in my products but it doesn't work. If anybody could provide any help I'd be extremely grateful.
