Mean girls 2 the movie

I just finished watching mean girls 2. It was a cute movie and I really liked it. I borrowed it from the library and right at the end it messed up so I couldnt see it or hear it right. It was all chopped up kind of like you push the pause button over and over. I was dissapointed that it messed up right at the end. I will have to see if the library has mean girls since I havent seen that.
