I tried installing iLife '11 even though I unknowingly already had it installed and I quit midway through the process. Now my iPhoto is screwed up and it has a white disabled picture for an icon.
When I click on it, it says
You can't open the application iPhoto because it may be damaged or incomplete.
How can I fix this? I'm pretty sure all my pictures are still saved somewhere but will everything still be in place once I fix my iPhoto?
