I uninstalled the App then cleared the store cache, deleted the left-over files for the App (C:\Users\User\AppData\Roaming\Facebook) then reinstalled it and it worked ^_^
Hi everybody, I am running win 8.1 and used the Facebook app for a while the I stopped using it. When I tried to login again after a while I can't login and it shows me an error !!! What should I do ? Thanks :)
