i have an imac with iphoto 11 version 9.1.5 it says it needs updating to be able to use icloud albums and launches the app store, however when i press update it comes up with the message 'To update this application, sign into the account you used to purchase it.' i have no idea what this means as it came already intstalled on my imac and my normal apple id isnt working to sign in with that. i have changed the email of my apple ID about 6 months ago, is this the problem and how do i fix it??
