It doesnt work on iPhone 5

Had to delete it and thank God when I went and re-downloaded it from App Store it gave me the previous version even though I still have the red dot on the App Store icon asking me to update!! But this latest update asks authorizations form twitter and when I go and try to have it I get the twitter server error! Please sort it out ASAP! Thanks!
