when i downloaded the app for my phone, it worked great at first. then suddenly i got logged out and cant log back in. theres absolutely no way someone has hacked my account either. so i tried to delete it and reinstall it 3 times and each time it told me something different. the first time it was, error validating access token: user (bunch of numbers) has not authorized application (bunch of numbers). second time, session does not match current stored session. this may be becausse the user changed the password since the time the session was created or facebook has changed the session for security reasons. third time, session is invalid. this could be because the application was uninstalled after the session was created. What does it all mean? lol and how do i fix it so i can play it on my phone?
