Macbook update 10/2015

Downloaded to my Macbook. When I open the app, nothing shows up. Then when I switched the size of the images all the wallpapers popped up but then they just started scrolling all the way to the bottom on their own. I could not track back up at all. Then when the scrolling stopped, I tried to go back up to the top but every time I scrolled up, it would scroll back down. I tried deleting and reinstalling but it didn’t work. Still no content on the standard format. Please help!
