hmm... cant really help you there then, you could try to blow dry the back of it to heat it up and get it a little stickier and try throwing it on the window real quick, ive never done this b4 but it might work. Maybe dont try it unless you have taken the whole sticker off, and only take the sticker off unless it just isnt staying on, if the edges are up you could blow dry them and sticking them, but it might create bubbles afterwards. I dont know but it might work?!?
