Can't update or open iPhoto after I changed my apple ID
Hi, I changed my apple ID username (i.e. email address) and can no longer open or update iPhoto on my mac. It's linked to my old user ID and won't let me change it even when I'm logged in with my new username in the app store. How do I work around this? Thanks.
iPhoto '11, OS X Mavericks (10.9.2)
