iPhoto won't open library
My computer shut down yesterday when a breaker tripped while work was being done on the house. Since then, I cannot open iPhoto: it asks for a library, with a blank field. When I browse for my library, it shows up, but won't open.
I have read previous threads. I have tried holding down alt & command while opening iPhoto, but it still just asks for a library with a blank field: it does not show a window asking whether I would like to rebuild or repair the library.
I am running OSX 10.9.5 on an iMac. iPhoto version is 9.5.1. I have the library file backed up via Time Machine on an AirPort Time Capsule. Everything is in the default places.
What to do?
iMac (27-inch, Late 2013), OS X Mavericks (10.9.5)
