Howdy FoxFifth! Thanks for the prompt reply. As far as I know, I have followed the procedure you outlined. When I look under Settings > iTunes & App Store it shows my new email address. I changed the email on my Apple ID a few weeks ago, and everything else has been working fine. I recently noticed my updates were not processing so I tried to manually update them. That is were it asked me to sign in with the old email. The actual message is "Sign into the iTunes Store. Enter the password for the Apple ID - " and that is where my old email address is. I tried using the new password, but that did not work. I have signed out and signed back in with the new apple ID on both iTunes and the App Store, and powered the iPad off after doing that. When I power back on and look at the bottom of the iTunes store and the App Store, they both show the new apple ID email address, but I still get the same message about signing into the iTunes store with the old Apple ID and email address.
Any ideas?
