I've tried to buy something on itunes recently, upon entering my password I keep getting an error message saying I have entered the wrong password (even though it's the one I've been using for years). So I followed the links, and reset my password. Although I can log in on apple.com in the "My apple ID" section with my new password, I'm still greeted by the "incorrect password" error on all other apple related products i.e buying things on itunes/ios/trying to log into icloud etc... any ideas?!! Thanks!!
