I'm very sorry for you man, because you seems to be a totally useless person if you were unable to use it wisely. You have installed the plugin on one site only, but even didn't try to use it actually (just installed and forgot about it). I believe you had no idea on what to do with it. So what can I say? Congrats sir, you are looser!
P.S. It sounds weighty when somebody says the product is shitty because "..." and gives some arguments to backup his point of view. But it always a sorry sight when someone calls the product shitty just because he has no idea on how to use it (your case), and course there are no arguments instead of "shitty", "cocksucker" and so on. You are acting like a spoiled kid who has broke father's Ferrari because the lack of driving skills. "It was shitty car, dad! I tell you it was shitty! boo-hoo"
