iPhoto 11 isn't working.
I recently added about 1000 pictures to my iPhoto library from dropbox. I then deleted the photos out of dropbox. Because the photos wouldn't work in iPhoto after deleting them from dropbox, I then decided to upgrade and buy iPhoto 11. After installing iPhoto 11, this message comes up when opened: "The photo library needs to be upgraded to work with this version of iPhoto." I don't have an external disk to use time capsle and I've tried rebuilding the database through iPhoto manager and through iPhoto. None worked. Please help. I've spent $15 on an app that isn't working. I know the deleted files must be corrupted or something of the sort. Thank you
