I accidentally deleted itunes from my ipad2 (don't ask). Using my mac, I downloaded the new itunes version 11 then synced my ipad. There was some kind of break during the download then it went on to finish. I don't know if this is important but I also downloaded the ios 7. It's great!! Since then my new itunes connect won't accept my password. It directs me to change my password which I have done 3 times. All other functions on my ipad accept the password just fine. I am not too computer savvy and I've tried all my tricks, so I need all you smart people out to help! Thanks in advance. SuziQ
