Upgrading iphoto 09->11 but 'modifieds' don't appear

Yes I already tried rebuilding8.1.2 several times. I still have 8.1.2 loaded and the library loads just fine with all the edits. It's just that iPhoto 11 rejects that library when I try to upgrade, as it just crashes. The iPhoto library manager trick worked great except for the big problem of 'disappearing' edits. I think the actual files are loaded onto the new compatible library I created but they aren't showing up on iPhoto 11. I tried rebuilding the iPhoto 11 library to make them appear but no luck.

Larry-

Point taken. The issue with this technique that you suggested is that iPLM defaults to rebuilding the library in 9.4.3 format, so it won't be able to be loaded into iphoto 09 before upgrading. I suppose I could uninstall iphoto 11 and start over and see if that works.

So this is the weird thing - When I look at the new library in iphoto 11 that I created under the iPLM explorer, all the edits/modified versions appear there but not in the actual iphoto 11. I tried rebuilding the iphoto 11 library again but no luck in solving the issue. Aside from reimporting the modified versions manually, not sure what else to do.

iphoto library manager allows you to explore the library created. WHen I view the new library that I created for iphoto 11 within the iPLM explorer manager, the photos that were edited appear edited. However, in iphoto 11, the pictures that have previously been edited do not appear edited. In fact, when trying to reveal in finder the modified versions, they only link to the 'masters' versions (even though I can actually see the modified versions are there in the file structure). Does that clarify?

SOLVED: Seems really stupid when you hear the solution, but I decided to delete iphoto 09 and leave just iphoto 11 as the only version on the computer. When I loaded the iphoto09 library into iphoto 11, now it started upgrading. Go figure. Thanks everyone for their help.
