Start of Something New- DW(Doctor/Rose)

Now I don't want you to think that I'm a crazy High School Musical fan or anything. I used to be when the 1st movie came out but since it became all commercialized(any kind of item branded with it!). I made this for my little sis who is :) I actually finished this one quite a while ago but Windows Movie Maker wouldn't let me publish it. Every time I tried it shut down my entire computer. Does anyone know why this is happening? Here you go, sis. Hope you like it! Ninth Doctor forever!!!! music is "Start of Something New" by Zac Efron and Vanessa Hudgens
