Now you should be able to change anything on your profile page. Click on your profile picture image. It will pop up your pictures that are stored to your computer. Once you have picked the picture, click and open it. A capsule will pop up for you to crop your picture. Once you crop your picture to your liking you need to click on the button that says crop image. The picture should now be your profile image.
