Re-activating a Facebook App
===

I want to know if it is possible to re-activate a Facebook App that has been previously disabled.

This is what happened:

We created a Facebook App and an iPhone App that connect to each other. After releasing our game to App Store, one of our programmers accidentally deleted the App from Facebook. Now players are shown a message saying the Facebook App does not exist.

We know this may not be possible, but still wanted to ask.

Thanks for your help
