I've been trying to update my iPhoto and iMovie because there updates out for it. but the app store will not allow me to update them. A window comes up that reads, "To update this application, sign in to the account you used to purchase it." the problem with that is i changed my apple e-mail/id as i no longer use the e-mail i had on it. what do I need to do in order to be able to update these apps? I tried to log in under my old e-mail but it would recognize.
