Can't get into Love Struck World

Hello,

I am going to try this again, because I have not gotten any responses back. But ever since I got the Love Struck pack, I am unable to get into the world that it comes with. I can't click anywhere and I have the same two worlds. How do I fix this? Do I have to disable or uninstall Love Struck? Do I have to buy it again after doing that? How do  I fix this?
