Dear members, The App Store on my iMac keeps giving me the following update message: -I don't even have Angry Birds installed on my iMac. -I used to have it a long time ago, but i unistalled it a long time ago. -I also can't update, because the Angry Birds that i had isn't linked to my Apple account. -Spotlight can't find any leftovers from the App, neither can Alfred. What to do?
