What's happening – Fav Talk Pro - Chatting about same interests Review

I try to sign in with my Facebook account and it keeps saying "sign in failed" when I try to select interests, nothing shows up for me to select. I'm unable to select any intersects. I'm also unable to select a nationality and a region. Without being about to select these things, I'm unable to move forward with creating my profile. What going on? I tried doing this on my iphone and on my iPod touch and it doesn't work on both. Nothing I do is working. I trying turning on and off my phone. I tried deleting and redownload ing the app. I tried everything I can think of. Nothing is working. The app was working earlier today and it was working perfect but all of a sudden it just stopped working and everything got deleted and now it won't let me make a account or sign in to Facebook or to my old account. It won't let me pick interest, it won't let me do anything. What is going on. Nothing works all of a sudden.
