Ok, Ok, ppl, found a way , FOUND A WAY !!!
First of all, push the pin to the anti-clockwise direction or to the arrow one. Then pull it up. Get something sharp like a knife. On the back of the top of the pin, like 90 degree direction, on the really back you will find a clamp - pull it a lil' bit up, but not too much so you won't break it and then, THEN, pull up the black screw. You will end up with the two pieces and something that's still holding them there. To get rid of that and finally pull out the push-pins, well, i still haven't found a way for that )). You can thank/swear/kill me later :*
