iPhoto won't open
Whether I click on if in my application folder or using my launchpad it just won't open. In fact nothing happens. It's as if I haven't clicked on anything at all. I have tried restarting my Mac but nothing?
I have a MacBook Pro and i'm currently running Yosemite.
Not sure where to start and any hep would be great, thanks.
MacBook Pro (13-inch Early 2011), OS X Yosemite (10.10.1)
