My Hubsan X4 H107D props spin but it won't fly.

My Hubsan X4 H107D's props are functioning but the quadcopter won't take off. I thought it was from a crash that took place the day before in which I flew at a high altitude and then lost control resulting in hitting the ground extremely hard, but I am not sure because it flew fine after the crash. Just now when I turned it on today it stopped flying. If you know please help. I have only had this drone for about a day now. It would be great if some one could help.
