How do you unhide apps on Facebook?

[Spock]

I hid an app game when I was not playing. Now I am playing and cant receive any posts from friends. The new lay out has me confused, since I have not found any button, or option to unhide it. I have clicked on given the app additional permission to post and send emails, but still nothing.
The application is not blocked. I just clicked on hide all on my wall posts when I was not playing. Now I wouldnt mind seeing the wall posts but none are being posted on my wall.

Go to Account ---> Privacy Settings ---> Applications & Websites ---> Edit Blocked Applications
Now you can unblock any applications that you had blocked!
