Aurellion Sol E won't go but 2 feet.

I just got out of a game where my E didn't go anywhere I would fly up but come straight back down. I had this happen my first game with him but it only happened a few times, this game it was constant. I thought I was doing something wrong and I read his E over and over again but could't figure it out, I even took some time to try multiple ways of using it. (Like taking my hand off the mouse after using it, to make sure I was miss clicking anything.) I'd like to know if anyone else has had this issue or if I'm just an idiot.
