I opened iPhoto 08 today and found all my events from 2009 gone! I panicked but did a search around and found out how to find my pictures through finder.

I found two folders - Modified and Originals which has the pictures in year folders. But I can't get iPhoto to rebuild those events. I store my iPhoto library on an external drive and did the Rebuild thing, I also tried manually telling iPhoto where to find my iphoto library but it still doesn't bring in these extra events from this year. All was working fine yesterday - what do I need to do?

Please help.
