iPhoto won't startup. It stops at upgrade on step 5!
Ok, I updated iPhoto when it asked me to in the app store, and now when I try to open it, it goes through 9 steps, but it stops on step 5 at 99% and won't finish opening. What do I do to make it finish upgrading to open it?
Also, I can open my iPhoto on my daughter's account, but on mine, the Admin account on the computer, it won't finished the upgrade.
