Whats happened to my iPhoto then?

[El Capitano]

Anyone experienced this one before?

for some unknown reason my iPhoto stopped working, I restarted the computer and launched iPhoto again. It came up and said something along the lines of trying to restart the computer and if that failed then hold command and shift when launching iPhoto to select a restore option.

I did this and was given about 7 options. I chose the restore library option and nothing happened.
I then noticed that there was an iPhoto update available in the Appstore and it said it fixed crashing issues. Perfect. So downloaded it.... now all I get is this message when I try and open:




I don't have Aperture installed so it seems I am now totally unable to get anywhere near a restore of iPhoto.

Any ideas?!

Quick to the Apple store and hope the staff aren't too busy with iPhone users
