I could do everything fine and then all of a sudden it kept showing me "invalid sever response." I can get notifications and everything, but I cannot see any chats, messages, walls, etc. I can't even email you guys because it's in game, and I can't even start a ticket because of the "invalid sever response" error. Please fix this, I've made some very good friends on this app and I have no way of telling them what's happening.
