Why won't my candy crush connect to Facebook?

[Nicola]

I recently deleted the app and was told that I would still be on level 168 when I re downloaded it. I wasn't. I was back to level 1. When I tried to connect it to Facebook the app just closed and went back to my home screen. It did this every time - even after I deleted the candy crush app again and reinstalling it. I even downloaded the Facebook app and used that app to connect instead of using the Facebook via the web. I don't know what to do now. Candy crush is telling me I'm on level one and that I have no friends on other levels. I've tried to connect to Facebook but the candy crush app Just keeps closing itself when I try.
Anyone help?
The device I'm using is iPod touch 4th gen by the way.
