iPhoto crashes after added map to photo book

Hi,

I have been creating a photo book in iPhoto (the current version) which I've spent a fair bit of time working on and customising over the last couple of weeks. I had pretty much completed this book when I decided to add a map to one of the pages (the bright green map). It added ok, but when I went to scale it to zoom out a bit it kept crashing iPhoto. I instead tried choosing one of the other themed maps and zoomed out to the distance I wanted. I then thought I would try go back to the bright green map to see if it would work now, it didn't and iPhoto crashed. Now, every time I open iPhoto and click on my photo book it crashes iPhoto without loading the book at all. I can't access or edit the photo book since making this change to the map.

Any support would be greatly appreciated as I've put a fair bit of time into this photo book and am hoping I haven't lost this for good. Even if I am able to just get the page layouts back if possible would be great.

Thanks!

Dan
