I cant find my video on youtube, help me to find it?

Hey...I am also using YouTube since four five years but I have never faced such kind of problem. Even I use to upload lot videos on it. Whenever I have to see them, I just have to type the keyword and my song is there. The problem you are saying may be due to the hacking of your Gmail account. There is also a possibility that some of your friend or someone who has deleted that video from your account. So just ask if somebody by using your account has deleted your video or not because you can only delete uploaded video from your own account. You can also type the right kind of keyword may be that is the reason your video is not getting displayed. Thanks and have a great time.
