IPhoto crashing one specific Book Project

Question

hi,
On the mac yosemite 10.10.1 and iphoto 9.6.
I just finished this one specific Book Project. Last thing I did was to change the map theme to the last one in the second row. This moment iPhoto crashed for the first time. Since then I was not able to open the project again because iPhoto is crashing every time I try to open this project.
It is not crashing on other projects, libraries or albums.
I already restarted the computer and restarted iPhoto several times.
I invested a lot of time so I will appreciate your help in getting back access to it.
kind regards,
Anna

Answer 1

Give this a try:
1 - launch iPhoto with the Command+Option keys held down to open the First Aid window. Be sure to follow the circled recommendation in the screenshot.
2 - run Option #4, Rebuild Database.
If this doesn't restore the book I doubt if there's anything the Genius bar can do to recover it thru the database files.  You may not even be able to delete the corrupted book as just clicking on it to delete may crash iPhoto.  If that happens you can either try creating a new book in the library or the following:
Using iPhoto Library Manager  to Rebuild Your iPhoto Library
1 - download iPhoto Library Manager and launch.>Click on the Add Library button,
2 -  select the library you want to add from those in the selection window.
3 - make sure that in the rebuild window the checkbox  "Scavange orphaned photos" is checked.
4 - now that the library is listed in the left hand pane of iPLM, click on your library and go to the Library ➙ Rebuild Library menu option
5 - in the next  window name the new library and select the location you want it to be placed. Click on the Create button.
Note 1: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments. However, books, calendars, cards and slideshows will be lost.
Note 2:  Your current library will be left untouched for further attempts at a fix if so desired.
The above will take less time than taking your MacBook Pro into the Apple store. But that's just my take of the Genius bar when it comes to iPhoto libraries.
Also you should strongly consider implementing a backup strategy ASAP.  If you don't you can count on losing file sometime in the future either from a software crash or a hardware failure, i.e. drive crash.  The easiest backup strategy to implement is to get  an external hard drive  and use Time Machine to backup your entire boot drive. Time Machine comes with every Mac and is located in the Applications folder.
