Facebook Game Won't Load

I am NOT tech savvy! I play diamond dash on facebook, and since I installed bitdefender, it will no longer load. It gets to 100% loading and then just goes round and round without starting.


I tried to copy and paste the URL to the whitelist, but it won't accept copy and paste, so I added https://apps.facebook.com but it still won't load properly. Tis never happened before installation of Bitdefender. I also don't understand all the different modes ie game, movie, standard etc. nor do I understand why or how this is supposed to change. thanks for any help :)
