Cool but I am so frustrated

This app is cool but every time I click on the design I want, nothing happens! I dont know what Im doing wrong, but I have been working on it for 2 hours! It finally did something in settings but then nothing happened to my key board. Im not a tech genius but I really need one! Someone PLEASE help me!!!
