Doesnt work

I downloaded it and when I clicked on it, it said that I need to log on to Facebook and error. So I logged on my Facebook and it still didnt work. I downloaded the Facebook app and logged on to that and it still said I wasnt logged on and error. So I finally went on my settings for my iPod and even added the account for Facebook and I was sure it would work now but no it wont let me on no matter what I do it just says error. The online it girl works just not this app.
